This is a great video. I've been practicing structural engineering in both the US and in NZ for almost 25 years now. Everything you said is spot on. To be honest, I probably didn't learn anything new, but it is so good to see this kind of practical and well informed resource for younger engineers on you tube. Good stuff. Thank you.
Is this a good video for a civil engineering student to prepare for summer internship at a structural eng. firm? Is this the general procedure used in this discipline?
i have been a structural engineer for almost 30 years and have my own cosulting practice. i love watching your videos. you dont miss anything and still manage to keep these videos short. keep up the good work. you are great teacher for young engineers. they should allbe watching.
When I first saw this video I was suspicious....A 'professional' giving forth this info? But having watched it through, I am impressed. Well done! I am 75 years old, still practicing: P.Eng, MiMechE. MiStructE.. With half a century in Structural engineering. most of it in Offshore O. and G. particularly with steelwork, from mudmats on the seabed to flarebooms at the highest point, and all the areas in between. The last 15 years being involved in design analyses and engineering for drilling facilities, typically with 2 or three support modules weighing up to 4000t. My work has included being Lead Structural Engineer(drilling) on the biggest in the world, (so far). I loved it all and I am still at it. Respectfully, listening to this young man, It is so good to see the future of our discipline is in good hands.
Hi Peter thanks for the support. Your job sound very interesting, with unique structural changes. Hopefully I can help young engineers improving their skills.
I've been working as a structural engineer for 10+ years and this video is stil helpful and filled with great insight. It's good to know how things are done in other parts of the world. Great videos. Always learning, or else we get stuck.
A shitty cadetship, a few recessions, no mentoring, but I still managed a full Civil Engineering Degree from UNSW. The details you talk about is exactly what I missed out on. I ended up managing civil structural construction and building projects. My engineering insights allowed me to make many critical decisions over the years that saved the client $millions. I have had a lot of 'adventures' in these roles and worked over seas and met some brilliant people. I have never structurally designed anything sadly, but I have seen some very dangerous designs by foolish and ignorant amateurs who were lucky I questioned their work. I am in my 70s now and appreciate your presentation and the mentoring it provides.
Hi Stephen, thanks for your support. Alot of designer ignore the construction side, your experience would be invaluable. Despite not designing any buildings your input made them.
@@BrendanHasty From the prebuilding side of the problem I have had a few projects redesigned and saved significant costs. My disappointment was that the financial bonuses at the end of the projects were often ignored. I did have 'mentoring' from 'hard nosed' construction managers who's detailed focus showed the benefit of hard work and the type of skill needed in the construction phase. Engineers are not good at self promotion but they are the ones 'sticking their necks out'. Sadly many of the 'good self promoters' were the dishonest shonks. Thank you for the chat.
I recently started working for a construction company and struggled a bit to understand the drawings until I came across your videos. I'm from a different engineering discipline. I really appreciate your videos, and I always hope that you will continue to make more for people like me. Cheers 🥂
Hi there! I am an architecture undergrad in Los Angeles, came across your channel, and found your video extremely insightful for my studies. Thank you for sharing! Looking forward to watching and learning more.
Thank you so much Brenden. It helped me a lot to understand the real happenings behind the design. Keep up the good work. More such tips are expecting from you. Cheers.
Hi Deepak thank you for dropping by. I am happy that it has helped you, this is why i do it. I hope my videos impress into the future. I hoping to build a commuity, so if there are any topics you would find useful let me know I am always up for sugestions. Feel free to share it around to anyone you think will find it useful. thanks again.
Excellent Video Brendan, keep up the great work! I'm a fellow Melbourne based structural engineer and that was a really good summary, cant wait to see your rules of thumb when you reach the 500 likes!
16 years ago i had an engineered Outback steel building erected on my property. The "contracter" unilaterally opted to change the design to save him money. Since he had taken this course, i was unable to pass it. I have hired 2 lawyers and 2 engineers (to reverse engineer it) to no avail. Now the county is demanding that i rectify or remove said structure. Your video has help me visualize the deficiencies in his changes. Thank you.
Excellent insight into engineering. I’m an Electrical Engineer and we are so closely related when designing projects. Thank you for sharing your knowledge .
I did not think that this person actually existed. An engineer that takes into consideration the fabricator and erector. After detailing and fixing the EOR's design for twenty years this is very refreshing.
Hi Andy, Thanks for the support. I think every design, well, at least a good design, should consider fabrication and erection. Building is hard enough to build without doing this. If it is easier to build, it will be a better building. I actually recommend that early on in the career of an engineer, they work on-site for a year or so; this gives them great feedback on their designs and how they can make it easier to build. but agree a lot of engineers do not, think that it is someone else's problem
Hi! Great video! About galvanic corrosion, the usual thing that happens in the project (esp. loosely coordinated ones, at least here in ID) is that another contractor came in without knowing what galvanic corrosion means, and starts welding stuff. Saw it once during my whole career (which isn't that long). It's really rare though. Most people here install the facade on the concrete surface covering the steel so everything should be safe. Also, should be noted for the international audience, that the rule of thumb works with the specification of mild steel where you're at. Chinese steel have slightly different standard.
This video was extremely insightful, hats off to you and your great work. I'm a civil engineering student in the Caribbean about to do my final year project on a steel structure so I'll definitely be taking this information into consideration.
hey Brendan great content! It would be awesome if you could do some calculation examples of various engineering concepts that the junior engineers may not have yet come across
Thanks for your support Tig K and watching. Good suggestion it could focus on small things that are often over looked and how I scheme and check designs.
Excellent. Galvanic reaction also severe when using Stainless Steel fasteners on steel, galvanized steel or aluminium. The bolt holes in the steel, GMS or Alu. will corrode aggressively and open up in size around each stainless steel fastener! Scary how few folks in industry know about Galvaniic Corrosion. Worth reading up on before doing design work..
This is very positive! I used to erect a lot of steel structures in a previous life as a rigger and crane driver and I can remember being so frustrated at the stupid design engineers who didn't think of how someone was supposed to physically put a bolt into a connection!! I'm so glad you're actually thinking about this basic detail!! I remember finding out that engineers in Germany had to do a years work on various projects as trades assistants before the could finally gain their full qualification and they seemed to turn out the best engineers in the world! No substitute for some real world experience!!
Hi Jono, thanks for the support, Good design requires engineering to know how the building will be built and the limitations that will be on site. I agree that all structural engineers should spend a year or so on-site to know the issues that will occur on-site. It makes you a much better engineer and will lead to better designs and better buildings.
Please make a video on the process of a design. What i mean is, say a client comes up to you and asks you to build a say 2 sory residential house for them and he beings along the architectural cad drawings, what do you do next ? Do you jump to etabs to build your model? And then what? How many reports do you write ? When do you write the reports ? Do you communicate to the project manager ? How ? I know that's a lot of questions but it would be really helpful and eye open for us students and new graduates to learn from you experiences . Thanks again Branden you are building a stong community of structural engineers in Australia 🙏🙏
Hi Marin, thanks for your questions it helps alot to guide my next videos. your comments are greatly appreciated. Hope I can provide future guidance that helps.
This is so great, so much information but I believe it would be spectacular with more visuals of either real world evidence of the topic covered (pictures/video) or graphics of the calculations. I really liked seeing the DWG's and beam formula. Without the visuals a majority of the content was out of my grasp
Hi James, thanks for the support. I would love to have more visuals to my videos, and have been trying to add more, it is just how much time I have available to do so, it can take hours.
Hi Bharath, I have a rules of thumb video ua-cam.com/video/Dz26PBnog4k/v-deo.html that will help size structural elements or did you mean a more specific design video.
@@BrendanHasty Thanks, I would be really intrigued to hear about your experience working with Architects. Especially finding compromise between aesthetics and practical/functional considerations.
Good work. Informative and clear directions. I am a big believer in watching engineering failure videos - a good learning tool. You are absolutely right that steel structures can have little redundancy, unlike reinforced or post-tensioned concrete. However, for all structures stability limit state design requirements should always be followed through to eliminate this. Ahhhh ........ sometimes easier said than done!
Hi Guy， thanks for your support. and total agree with reviewing past failures to ensure you learn from them. Good design should be always the number one goal.
I'm learning two way slabs right now, looking for a book about messy column placement. I've seen alot of examples that could only be designed in a computer, but would like to be able to do it by hand.
This is interesting !! so amazing Sir! Can you please send the book pdf and also what is considered fulfilment design safe or not, and what is the consideration before the start designs steel structure? what you use software to design. Structure? if you use the Solid Work application can you send the how-to-do load analysis on this application step by step? Looking forward to your reply !!! Thank and regards
Interesting about vibration comfort. How you check steel structure with frequency above 10 Hz and low mass of structure? Example SCI P359 low mass it’s problem, and they doesn’t say about limited frequency after which you don’t need check structure.
Hi Arter, you need to have sound damping below the floor and isolation pad, connection to walls and beams need careful consideration. Mass and volume is the only real way to solve it, so adding a concrete floor would help.
hi can you recomend a type of ibeam i should be using for supporting the weight of 6 x 40 ft shipping containers wanting to build a structure that is 2.5 metres high which the 6 shipping containers could sit on top of 3 on the first floor and 3 on top and under the containers could be used for a garage the width and lenth will be 9mtres by 12 metres
I'm a little confused about steel becoming the anode when there is a connection aluminium. Aluminium sacrificial anodes are commonly used on steel craft in salt/brackish water. Am I missing something?
Hi Jake, it can at times seem best to weld everything however you can induce unexpectes stresses that you will need to deal with. thanks for the support.
Great video, would liked more photos and videos shown to explain what you are saying, i had some difficulty to understand some things you said, perhaps that's because i am junior ^^
Hi Pooja Hegaje, thanks for the suggestion on topics to cover. this video should have help uncover some of these rules. hope you enjoy my future content.
22:26 Opposite. Aluminium alloys are less noble than steel*, the aluminium will become the anode and corrode**, not the other way around. * Despite being more reactive, aluminium corrodes in alkaline environments, and, in general, the environment is rather acidic. Steel corrodes faster in an acidic environment, so in the end steel is more corrosive - but this is because of typical environmental characteristics rather than the material itself. ** Providing the volume of the anode is equal to or smaller than the cathode.
Hi Suhaid Khan, in design I typically will do an upper and lower bound assessment. so for deflections check the connection as pinned, but when pre-camber assume it is fixed as you don't want to have the structure hogging. This would be similar to ultimate design.
Really you increased my information, professional explanation, keep going, Your advice I have spans 27 meter, &high 10 meter, which design suitable, for high winds effect, thanks in advance
Hi Qasim really depends on what internal structure you have, it is a open space or internal walls, you will likely need internal support at or so 8-12 meter centers. High wind loads are also subjective.
@@BrendanHasty thanks for valuable reply, First Merry Christmas & prosperity and healthy life, Actually two floors concrete building highly columns concrete 8 metres, Above the concrete columns, the roof from steel structure cover the facilitie, The maximum span between the concrete columns is 27 metres,
Hi it depends on how the building is being built. this can vary alot. if you have slab you need to take into account a minimum of a 2kpa live load plus SW of the slabs and propping loads. Some times you also need to consider temporary stability loads. it is something you need to guess at the start and refine when the builder is involved. thanks
Hi Brendan, You have summarize the latest 8th edition steel designer's handbook in this video!! Good on you 👏 What do you think for 310UB32 spanning 13.97m, not precamber with Z15015@1200mm. With typical Australian loads on non trafficable warehouse roof!! My calculation shows that's beam fail for serviceability but I saw it on recent warehouse design in Perth. Keep it up.
Hi Ahmad, I haven't done the numbers on that, however, how much is it failing by? Typically I find that long span steel roof are governed by deflections, and that is an easy calculation. there is a natural pre-chamber in a member that may be helping. Also, what are the end fixities this may either make it better or worse.
Hi Dries, thanks for the support, Aggree that sometime the music may have been too loud. always looking on making the audio better, thanks for lettting me know.
Hello from Perth, The video is great; if you ever get time, please consider some simple worked examples from the Steel designers handbook, to show steel sizing calculations. Maybe can do some Spacegass steel sizing examples for simple structures. Do you use much excel spreadsheets for steel calculations?. I try to use all three of these and am wondering your methodology . Also, how do you document the finished steelwork; for example Spacegass reports? do you use the built in report generator? or document each beam seperately etc.
Typically I use Excel or mathcad to design simple structures. When modelling in spacegass I use the rule keep it simple KISS, complexity complicates checking the design. And typically I build up the complexity of the model simple to more complex in stages if a complex model is required. Will likely make a video on my work flow.
What would you classify a composite steel and deck with say 6" of cast in place concrete for the floor structure's diaphragm to be: rigid, psuedo-rigid, semi-rigid? Would you transfer lateral forces 100% through the floor system to the cores/braces/moment connections? center of mass and center of rigidity are close to eachother. Thanks
Hi Peter Typically, I model it as semi-rigid. Computers are powerful enough nowadays to model them as semi-rigid. The lateral forces transfer through the floor system to all the stability support. Center of mass is just a simplification; when COM and COR(Center of Rigidity) are close, there isn't much torsion.
@@BrendanHasty got it thanks for the response. Yea I like the way the lateral system reacts when modeled as semi rigid as it seems to be a more accurate representation of what occurs in real life I would think. I have another question: when I design a steel building I like using as deep a beam as I’m allowed not only for its cost of efficiency but I find that the couple created at the column connection is greater even though we say the connection is simple and moment is not transferred to the column via the beam flange, in reality dont we have a small amount of moment going into all the columns when the diaphragm moves?
@@BrendanHasty i do the same, but it's comforting to know that others do so too. very often in europe colleagues concentrate on calculating the beams, neglecting the connections and above all dedicating very little time to shop drawings and feasibility. for steel I think it is essential to know the processes in the workshop, the different tools they can use, how much space an operator needs to screw a bolt or to weld two sheets of metal, hanging in the air at a height of 8m maybe
@@peeolo Thank you for thinking about how the welder is gunna be able to weld that. The struggle is real sometimes… As a structural Ironworker one thing I notice that is missed quite often is deck support around columns.
@@jordzzzzzzz i was a bricklayer and truck mechanic before to become an engineer. People Need to work with my drawings. They're not piece of art or "some pretty nice sheet of paper". Thery are fabbrication drawing....for fabbrication not for art
Hi Prabin, If i get 500 thumbs up I will do the complete rules of thumb design for steel. Not sure what that would equate to in comments =D. hopefully we get there.
For the rule of thumb of Steel design. See this video ua-cam.com/video/Dz26PBnog4k/v-deo.html
i am already dead of confusion of maths of buildings
How much is each steel bar by meter length? Once the steel bar are installed and bolted can hard wood be used rather than hard concret blocks?
"Rule of thumb" comes from the maximum thickness of a stick you were allowed to beat your wife with. Just sayin'
Yes, he should use more info graphics explanation.

You are absolutely right that steel structures can have little redundancy, unlike reinforced or post-tensioned concrete. However, for all structures stability limit state design requirements should always be followed through to eliminate this. Ahhhh ........ sometimes easier said than done!
Hi Guy， thanks for your support. and total agree with reviewing past failures to ensure you learn from them. Good design should be always the number one goal.
I'm learning two way slabs right now, looking for a book about messy column placement. I've seen alot of examples that could only be designed in a computer, but would like to be able to do it by hand.
Hi CanadaNickciN, have you tried yeild line? that should allow you to design it by hand.
@@BrendanHasty Not yet, aha! thx!
This is interesting !! so amazing Sir! Can you please send the book pdf and also what is considered fulfilment design safe or not, and what is the consideration before the start designs steel structure? what you use software to design. Structure? if you use the Solid Work application can you send the how-to-do load analysis on this application step by step?
Looking forward to your reply !!!
Thank and regards
Hi, congrat is a amazing video; In my case I state two analysis: calculus (only frames to resist loads) and design (drawing).
Hi Fe Lix thanks for the support. Glad that you enjoyed the video.
Good work please show more details on drawing
Hi Kamal, thanks for watching. I will work on showing more detailed drawing in future presentations.
Thanks. Good information. Constraining and stray supports.
Just a point to ask on plumbing a!structure and how can you pl. tell about it
Interesting about vibration comfort. How you check steel structure with frequency above 10 Hz and low mass of structure? Example SCI P359 low mass it’s problem, and they doesn’t say about limited frequency after which you don’t need check structure.
I like BS 449. Simple.
And prefer to design mostly as simply supported member.
How to limit the noise vibrations of someone walking on steel floor or stairs? Can you please elaborate on solutions, Thanks :-)
Hi Arter, you need to have sound damping below the floor and isolation pad, connection to walls and beams need careful consideration. Mass and volume is the only real way to solve it, so adding a concrete floor would help.
Hi, thanks for the help you've been doing by sharing these information. Can you give some information on buildings with steel frame and concrete core
Will do Sharon! I have added to my list.
hi can you recomend a type of ibeam i should be using for supporting the weight of
6 x 40 ft shipping containers wanting to build a structure that is 2.5 metres high which the 6 shipping containers could sit on top of 3 on the first floor and 3 on top and under the containers could be used for a garage the width and lenth will be 9mtres by 12 metres
depending on they layout the shipping container maybe able to span the distance without a beam.
I'm a little confused about steel becoming the anode when there is a connection aluminium. Aluminium sacrificial anodes are commonly used on steel craft in salt/brackish water. Am I missing something?
A a structural welder and civil engineering student I want to weld everything. But it’s the most expensive and time consuming
Hi Jake, it can at times seem best to weld everything however you can induce unexpectes stresses that you will need to deal with. thanks for the support.
Great video, would liked more photos and videos shown to explain what you are saying, i had some difficulty to understand some things you said, perhaps that's because i am junior ^^
Hi Brooks thanks for the suggestion, i will look into improving. Also, maybe i was talking too fast. hope to impress is my future videos.
Brilliant Brendan . A lecture on gravity based onshore wind turbine foundations would be great...
Hi Imran, thanks for the support and suggestion.
thanks for post this lecture. very useful. i need one detail. what type software tools is used for making shop drawing detail
Take a look at Tekla Structures.
@@johnduncan7871 thank you
Greatings from India. Wanted to know about the industrial buildings design as I'm a fresher in designing field.
Hi Pooja Hegaje, thanks for the suggestion on topics to cover. this video should have help uncover some of these rules. hope you enjoy my future content.
Thank you !
Your welcome
Professional experience,
look at my Linkedin it is linked on my channel pages.
22:26 Opposite. Aluminium alloys are less noble than steel*, the aluminium will become the anode and corrode**, not the other way around.
* Despite being more reactive, aluminium corrodes in alkaline environments, and, in general, the environment is rather acidic. Steel corrodes faster in an acidic environment, so in the end steel is more corrosive - but this is because of typical environmental characteristics rather than the material itself.
** Providing the volume of the anode is equal to or smaller than the cathode.
Thanks for the correction. It is good to learn new things.
@@BrendanHasty, I'm thankful as well. Nice video, learned quite a few things from it.
Are there any minimum spans before one can provide fly bracing or it should be provided at all times
Thanks brother , please clearify in structural system where we should give realease the elements in modal better. what will effect in site.
Hi Suhaid Khan, in design I typically will do an upper and lower bound assessment. so for deflections check the connection as pinned, but when pre-camber assume it is fixed as you don't want to have the structure hogging. This would be similar to ultimate design.
Very interesting video.., thanks
Thanks for watching AL Edz.
Really you increased my information, professional explanation, keep going,
Your advice I have spans 27 meter, &high 10 meter, which design suitable, for high winds effect, thanks in advance
Hi Qasim really depends on what internal structure you have, it is a open space or internal walls, you will likely need internal support at or so 8-12 meter centers. High wind loads are also subjective.
@@BrendanHasty thanks for valuable reply,
First Merry Christmas & prosperity and healthy life,
Actually two floors concrete building highly columns concrete 8 metres,
Above the concrete columns, the roof from steel structure cover the facilitie,
The maximum span between the concrete columns is 27 metres,
Thanks Brendan for the hints. Very Insightful. Glad I watched. :-)
Hi Ryan, Thanks for watching. glad that your found it insightful.
Hello Brendan
Big fan of your videos
What is the construction load that i should i applied in steel Design
Hi
it depends on how the building is being built. this can vary alot. if you have slab you need to take into account a minimum of a 2kpa live load plus SW of the slabs and propping loads. Some times you also need to consider temporary stability loads. it is something you need to guess at the start and refine when the builder is involved. thanks
I had a temp job in college doing steel detailing. I wish I would have known this then instead of learning on the job.
Hi Epistte, agree learning on the job cam be time consuming, wish I had posted this early to help you out sooner.
@@BrendanHasty The temp job was in 1989. I'm old. Obviously pre-internet and pre-CAD. Everything was on vellum.
Hi Brendan,
You have summarize the latest 8th edition steel designer's handbook in this video!! Good on you 👏
What do you think for 310UB32 spanning 13.97m, not precamber with Z15015@1200mm. With typical Australian loads on non trafficable warehouse roof!!
My calculation shows that's beam fail for serviceability but I saw it on recent warehouse design in Perth.
Keep it up.
I forgot to mention that the spacing between rafter is 6.5m.
Hi Ahmad, I haven't done the numbers on that, however, how much is it failing by? Typically I find that long span steel roof are governed by deflections, and that is an easy calculation. there is a natural pre-chamber in a member that may be helping. Also, what are the end fixities this may either make it better or worse.
@@BrendanHasty hi Brendan, I have sent you an email. Thank s
Why did some of the steel Industry change over time from A7 and A9 structural steel to A36.
10:37 In what units is the δ in that formula, mm I suppose right?
Correct this will be in mm
Great video
Glad you enjoyed it, and thanks for watching!
Keep going, you are amazing. You have added something, I can’t find it on the books
Hi Ghaz, Thanks for watching, Steel takes time to master hope my tips help you master steel design.
X2 it's like re discover a world that you already know
Sir, can you please suggest/refer any document or book for the steel structure detailings with examples?
Really good video, everything was explained very clearly. The music was sometimes a little too loud but that's just my personal opinion.
Hi Dries, thanks for the support, Aggree that sometime the music may have been too loud. always looking on making the audio better, thanks for lettting me know.
Great Words
Thanks for the support Ahmad.
Very nice
Hi Sabe thank for the support
How about explaining why the WTC went down??
Hello from Perth, The video is great; if you ever get time, please consider some simple worked examples from the Steel designers handbook, to show steel sizing calculations. Maybe can do some Spacegass steel sizing examples for simple structures. Do you use much excel spreadsheets for steel calculations?. I try to use all three of these and am wondering your methodology . Also, how do you document the finished steelwork; for example Spacegass reports? do you use the built in report generator? or document each beam seperately etc.
Typically I use Excel or mathcad to design simple structures. When modelling in spacegass I use the rule keep it simple KISS, complexity complicates checking the design. And typically I build up the complexity of the model simple to more complex in stages if a complex model is required. Will likely make a video on my work flow.
What would you classify a composite steel and deck with say 6" of cast in place concrete for the floor structure's diaphragm to be: rigid, psuedo-rigid, semi-rigid? Would you transfer lateral forces 100% through the floor system to the cores/braces/moment connections? center of mass and center of rigidity are close to eachother. Thanks
Hi Peter Typically, I model it as semi-rigid. Computers are powerful enough nowadays to model them as semi-rigid. The lateral forces transfer through the floor system to all the stability support. Center of mass is just a simplification; when COM and COR(Center of Rigidity) are close, there isn't much torsion.
@@BrendanHasty got it thanks for the response. Yea I like the way the lateral system reacts when modeled as semi rigid as it seems to be a more accurate representation of what occurs in real life I would think. I have another question: when I design a steel building I like using as deep a beam as I’m allowed not only for its cost of efficiency but I find that the couple created at the column connection is greater even though we say the connection is simple and moment is not transferred to the column via the beam flange, in reality dont we have a small amount of moment going into all the columns when the diaphragm moves?
@@BrendanHasty i do the same, but it's comforting to know that others do so too.
very often in europe colleagues concentrate on calculating the beams, neglecting the connections and above all dedicating very little time to shop drawings and feasibility. for steel I think it is essential to know the processes in the workshop, the different tools they can use, how much space an operator needs to screw a bolt or to weld two sheets of metal, hanging in the air at a height of 8m maybe
@@peeolo Thank you for thinking about how the welder is gunna be able to weld that. The struggle is real sometimes… As a structural Ironworker one thing I notice that is missed quite often is deck support around columns.
@@jordzzzzzzz i was a bricklayer and truck mechanic before to become an engineer. People Need to work with my drawings. They're not piece of art or "some pretty nice sheet of paper". Thery are fabbrication drawing....for fabbrication not for art
Great job keep up good work thank you
Thanks famo, thanks for the support.
Hi Brenden, I am loving your contents. Will you please make videos on Seismic Zones and Ground motion parameters.
Thank you for your suggestion! I have put it into my planned video topics.
Excelent didatic, congrats
Thank you for watching Ana!
Any advice on doing structural engineering? It is still rewarding financially?
Hi Leb leb, i enjoy it. tho I do wish i was paided more.
How can I prevent cracks in partition walls due to deflected structural beams' interaction?
Thank you Brendan. How many comments you need to do bring thumb design video ? :D
Hi Prabin, If i get 500 thumbs up I will do the complete rules of thumb design for steel. Not sure what that would equate to in comments =D. hopefully we get there.
