The value of "s" taken by asutosh sir is zero for normal building. And the gust factor is fixed for a normal building. The value of the G is also shown fixed in GSDMA DOCUMENT calculation WO7 !!
Thank you sir. Your video is very useful for students like me who wants to learn actual method to calculate wind loads. Thank you once again and I hope you will make videos on things that are not clearly explained in internet🙏🙏🙏
Sir for calculating K2 factor you are using formula from 6.4 and suggesting to use the table 2 alternatively, but the min. Value for K2 for category 1 is 1.05 and you are getting 0.7 for 52mts, so please clarify.
Static method main - Pressure coefficient method and force coefficient method aate hain to ye 2 methods main se konsi linear static main aati hain konsi non linear main aati hain?
Dear sir, Do we need to consider dynamic wind pressure for structures having height less the 4 meters? Please respond and if no please tell the clause of IS where it is clearly mentioned
During wind load, we consider the directions in terms of angle.. so if along is 0 (+x)degree then across will be 90 (+y) degree direction.. if along wind is from 180(-x) degree direction and across will be in 360 degree direction(-y).....
Hi at one place there was difference in natural frequency was found so u told that it is stiffness based model then u took some other exam model. I could not understand that please explain a bit Thanks
We need to consider 2 conditions basically, Service condition and Ultimate condition ..and it can be by assigning appropriate property modifiers to the structural elements
Turbulence intensity is not same for all height for a particular terrain catagory it will change with variations of height ,so r value will also change in each story level
When design wind speed is variable with height then how wind gust gonna be the same? There are basically 2 approaches.. if u finding total force to the structure to be applied at Top most story then u take all max and calculate Gust factor and force... if u r applying story lvl forces then it will be the same as shown.
@@ilustraca In etabs while designing, many beams fails in shear, o/s etc. Pls mk a video for same. Especially short span beams between column/ walls. Then need to design with steel beam theory, bit uneconomical..pls give sm economical soln for same in etabs or RCDC
Could u pls guide to check displacements limiting values, I am doing as shall be less than H/500 at each corner at top. Pls guide with supportive clause in code.
Mass participation has nothing to do with stiffness modifiers.. Stiffness modifiers are used to take the cracking affect into account under specific loading criteria. Modal analysis is for understading the fundamental vibration pattern of the building and modal mass participation tells what percentage of total seismic mass is vibrating in each mode. We had detailed discussion on the same. You may find it in our UA-cam channel.
Again this video is about Gust factor calculation and there are few mistakes observed in the video later. I would be happy if you could arise questions on those.
Mass participation depends on your geometry. How can you say this that it's nothing to do with the stiffness modifiers. You will get different results for both cracked and un-cracked modifiers bro.
Could u pls make a video of details to apply in etabs after getting values of along & across wind from excel. Right from applying load pattern, mass source, load case, load combinations, & viewing results. Pls guide
In most of the cases the frequency would be lesser than 1 only for the first mode, where it comes under the second criteria whether it is necessary to do dynamic wind analysis for all the building.....
For across wind you calculated the turbulence intensity, for that , in terrain category 4 you used 0.67 *z but the 0.67 is not mentioned in code. Whether it is correct or wrong

Excellent job 👏 You have covered everything that gave complete clarity of design. Thank you very much 🎉 keep it up
bro you are doing an excellent job ,...really inspiring. many many thanks to you
means a lot !
very good detailed description.........
Thanks a lot.👍👍
Your Videos are very informative to us. Thank you sir
Very well explained, just for CFs calculations make sure that data validation in excel is in ascending order.
awesome explanation...big fan of your channel...
Thank you..

Very Informative... Thanks...
Thank u sir for explaining this method
Hi it is definitely a excellent job.thanks .if possible please share excel sheet
respected sir,
why you have taken time period for first mode shape,
and what is the uncracked condition (WSM)
keep going bro
Very Very helpful. Can you provide calculation for Peak Acceleration
Sir wind analysis kon kon se methods se kr sakte hain?
Static method- Pressure coefficient method and force coefficient method
Dynamic - 1. Gust Factor
2. Wind Tunnel
Sir static method main response spectrum method se bhi kr sakte hain kya wind analysis?
Response spectrum is Dynamic Seismic Analysis Method..
Do not confused between Seismic and Wind Analysis
Static method main - Pressure coefficient method and force coefficient method aate hain to ye 2 methods main se konsi linear static main aati hain konsi non linear main aati hain?
Dear sir,
Do we need to consider dynamic wind pressure for structures having height less the 4 meters? Please respond and if no please tell the clause of IS where it is clearly mentioned
How much limiting values for Displacements chk when we apply gust factor..H/500 or anything less..
Sir, how to find the load for different return periods please explain.
Thank you very very much sir 🤗😊..
What is use of last two columns in last tables like Wsx, Gdx.
Also values of Z1 to Z4..IF value on IS pg 45...pls guide
make video of detailed Etabs to RCDC
When to use table 2 for k2 values please if you could tell?
In case of Rigid structures when you are not using Gust factor and Design mean wind speed.
@@ilustraca thank you
@@ilustraca thank you
Hi. Great job..I have a doubt. If along wind direction is in +ve X direction then across wind would be in +ve or -ve y direction?
During wind load, we consider the directions in terms of angle.. so if along is 0 (+x)degree then across will be 90 (+y) degree direction.. if along wind is from 180(-x) degree direction and across will be in 360 degree direction(-y).....

Sir how to determine 'Zo' to determine K2 for diff terrain catagory???
Reply plz
Hello Sir, Across wind Load formula values in your Excel Sheet is not correct...
Can you please explain me how to take s and Z in gust factor as I am confused in it please
Turbulence intensity is not same for all height for a particular terrain catagory it will change with variations of height ,so r value will also change in each story level
Sir, where we do this wind dynamic gust factor analysis or we can say the basis criteria of this analysis where we can apply ?
Mentioned at the very begining.. plz do watch
Vh,d in G Gust Factor calculation you have considered height as variable. it should be fixed value for building height h. Please reply
When design wind speed is variable with height then how wind gust gonna be the same? There are basically 2 approaches.. if u finding total force to the structure to be applied at Top most story then u take all max and calculate Gust factor and force... if u r applying story lvl forces then it will be the same as shown.
you used h as variable in calculation of SIZE REDUCTION FACTOR 'S'. the formula has Vh,d. Note h. it is note z or s@@ilustraca
Sandip Thanks for reply, Cross wind response base MOMENT is too high with IS875 formula for 100m high str. You may studies. Any suggestion
Sir please show the calculation of K2 example as I am unable to match the value.
Pls make a spl video for wind static & wind dynamic analysis in etabs
already these are explained in great deatail here... rest you can enroll to our advance course for more better understanding!

doing good job 👏 how much cost for full course etabs and safe including xlsheet and design notes

@@ilustraca what is zo value for terrain category 2 and 3
Why did you check for un-cracked modifiers for time period?
Please make the question more clear...
@@ilustraca you have considered un-cracked modifiers for modal mass participation.
I want to know why?

Yes.. if slender structure then also Dynamic effects need to be considered
