Good job. Please keep the videos coming!
Thanks Zee
Really good video mate, goes through everything. Well done.
thanks a lot. Appreciate your support!
such valuables tip mate! thanks a lot. Keep it up.
Thanks Marcos
Wow. You made best video ever!!!!
Good on you mate👍👍
thanks my friend
Thanks a lot. This is really educational.
Thanks for the support Thilan
Hi mate good job
Please can you make a video about steel beam and floor joist in residential housing
Thank you
Hi Nacer...what about steel beam and floor joists would you like to know? I have a video on how to design a steel beam on the channel
Really clean explanation- what software has this ?
Can you please share for calculation of waffel slab for concrete and reinforcement
Yeah. I will put it on the to do list :)
AS2870 have raft slab and strip footing table , can you more clear when i can select raft or strip footing please as i am little bit confuse. thanks your video aawesome
My interpretation is that strip footings are usually for masonry walls and they run underneath the slab (tied or not to the slab). A raft would be a single stiff element. This is how I see it.
Wow, as a structural engineer migrant who just arrived and hunting for jobs in Australia, I feel this vedio is really infomative and instructive to help me get familar with the Australian structural engineering work. Thanks mate and hope to see more this kind of instruction vedios in the future.
Thanks for the feedback Luke. Good luck on your journey. Don't forget to have fun. Cheers
Hi mate, would you able to do a video about Strip footing design ( specially for H1-D.. sites )
Hi Kasun. I will add to the list for sure. Thanks for the suggestion
Quality explanation. Can I get a copy of your structural notes sheet?
Send me an email and I will send it to you
Amazing video thank you. May I please ask 1) if the concrete floor is going to to have a grind and seal, what is the minimum specifications you'd recommend. Could you get away with N25. 2) how much extra thickness do you specify for a polished concrete slab compared to a standard?
I would up to N32 at least. The price won't change much and you will have a better finished product. SL82 mesh, but SL81 is ideal. Cure the slab with plastic for 7 days. Top cover around 35mm. Have a look at CCAA polished concrete guidelines if you're unsure.
@@bengthebrazilianengineerinAus Thank you and i'll get you to do the engineering for this when we are doing the plans. With my best wishes, NIrosh
@@joshkwd8527 Sounds good Josh. Looking forward to it. Feel free to reach out to me anytime.
@@bengthebrazilianengineerinAus I will do for sure bro, I am Deigo's friend btw - small world!
Hi there,
If you can put more information about slab and footings. AS2870.
Thanks
Will do. Thanks for the suggestion
Hi thanks for your videos. I have a project, 600 edge beam however below the edge beam the engineering drawing show 400mm min blinding concrete to original soil with 100kpa bearing capacity.
Should do 2 pours for this? Should I install the vapors above the blings? Thank you
typically 2 pours and the blinding layer can be of lower concrete grade (refer to your engineering drawings). vapours can be above. What type of soil do you have?
@@bengthebrazilianengineerinAus great thank you. Class M, But soft fill is observed top 1m...
@@ningchen6242 footing depths are typically between 300 and 400 for class M depending on the type of construction. I would have done some backhoe pits or piers to go through the fill. The blinding layer works as well, but you may end up using more concrete.
@@bengthebrazilianengineerinAusvery much appreciated your reply. if I go with bore pier, what spacing it should be normally?
@@ningchen6242 It's specific to each project. I would ask your engineer. I can't give you advice on that on UA-cam.
where is a design example for a residential slab? I can't find anything and AS 2870 doesn't have much.
Very helpful, thank you!!!
Thanks for the support
My off the plan house builder is going with M-class slab for p class site 85mm thick 20mpa waffle pod slab for a double storey house. My worry is M slab okay? Builder offered only minimum 6 years structural warranty. Do you suggest anything I can do or say to builder now as only the piering done as of now.
Hi mate, firstly you need to look at the soil test and understand why the site has been classified as P. It could be due to presence of trees, soft soils etc. Class P may not necessarily be bad. Possibly the expected surface movement of you site is for class M, hence the reason your engineer designed the M-class slab. If you are unsure, email your engineer.
@@bengthebrazilianengineerinAus
Bit concern about having M-class slab design by structural engineer on a p class site, usually seen them specifying H class slab. Interestingly the block behind
mine has the same model house (80% completed) has H class slab but for ours the same engineer specified M-class.
Read few horror stories about
slab heave and our warranties is only 6 years. What are the preventative measures that can be taken to avoid slab heave issues?
Read that concrete apron around does help? Thanks mate, your video was very informative. As an engineer myself, I appreciate & feels good when educating people on fundamentals which can help them in real life.
@@rsg5850 Not a problem. Happy to help. If you google "minimizing foundation movement QLD" or something in this line you may find good guidelines
@@bengthebrazilianengineerinAus legend!
Is there a standard in Australia for the design life of structure and foundation for residential build?
Would you please make an Video for waffle slab
