AF Math & Engineering Thank you sir , vary halp full this vedio

[@faribasalimi9397]

It was a great help to give me a sight on how to apply wind load.This video was exceptional much more helpful than other videos on wind load.

[@faribasalimi9397]

would you please do one on flat slab design.I dont know where should I place hidden beams and how to divide panels to have a better load distribution.Thanks in advance.

[@AFMathandEngineering]

Thanks for the comments. Laying out structure and hidden beams comes with experience designing slabs. On e you do 20-30 slabs youll get a feel for it!

[@mukhalladmurad6877]

Please your video very clear but please complete the analysis with load combinations We have dead and live and wind . When we want to combined it with wind load (we have 12 case generated by the software) which case will use it in general combination equations

[@dinawissam5658]

I was struggling to find videos of people using the NBCC so this was super helpful, thank you!

[@AFMathandEngineering]

Great, glad to hear that! Thanks for the comment!

[@Mohsinbagban]

Nice. Wanted to learn this as the structures i design have different floor plans and applying load at C.M. is difficult at it varies with height and using exposure from shell objects is also not right at at multiple locations there's no slabs but walls and v/v.

[@adambro2012]

Very insightful video, however is there any tutorial on how to assign wind loads for circular surfaces, I feel like it gets tricky when considering the direction and since we are not defining a direction I wonder how it has to be assigned (in the form of exposure to shell elements)

[@ahmeddaif6622]

Great video, what about the wind load upon the roof ?

[@gdeepika1205]

How to model CFDST (concrete filled double skinned tube) and analyse it in ETABS I have modelled but it isn't recognised as a composite column in ETABS and hence can't be analysed as composite column. What to do?

Thank you so much! You just helped me with my whole dissertation.

Wow, great to hear! Thanks for the feedback, good luck defending!

[@konanblejustin855]

Great video. So clear to understand. Thanks

[@hariasssss]

for duo pitch roof structures how have to apply pressure co efficients ?.. Because there is only two surfaces and how to apply different pressure coefficients for 0 and 90 degree

[@puspitarahmasari6841]

Hello sir, its a really good video. as in ASCE 7-16 that the minimum wind load is 0,77kN/m2, can i just input them to the cladding as distributed load, same way as we input shell load for floor plate but in local axes this time. thanks in advance.

[@AFMathandEngineering]

Thanks! I'm not sure about the ASCE but if you're going to use this method yes you should input as a distributed shell load, however in most cases the code requires a linearly increasing wind load which is difficult to apply here. Also most buildings are not going to have the minimum wind load and you'll have to calculate that load. In the case where you have a multi story building I suggest applying wind load using diaphragm which is more accurate code wise.

[@tuklapG]

sOO which is better? Applying loads using claddings or using diaphragms?

[@AFMathandEngineering]

For actual code design diaphragm is far better, you can better input code parameters and have more control over your loads.

Hi you! When wind load active per x direction, still have zone A.B.C at Y direction have value, how about that in Etabs?

[@AFMathandEngineering]

Sorry don't quite understand the question?

[@dungnguyenthanh6390]

[@LEBMG34]

Hello, is there a specific way to draw the cladding. i did the same steps you did but when i draw the Cladding nothing shows up (its as if i didn't draw anything). Can you please let me know if there is any setting that i should have on? if not is there another way that i can apply the wind load onto the columns and beams directly in the direction that i want (lets say in the x direction)?

[@AFMathandEngineering]

You probably have visibility of null shells turned off. Try turning them on it should fix the problem.

[@AFMathandEngineering]

Also, for actual design it's recommended you apply your wind load directly to diaphragms, see our video on this topic here: kzbin.info/www/bejne/gXnFYaB3d6iinKc

[@LEBMG34]

@@AFMathandEngineering ok perfect thank you soo much i will try that out.. sorry one more thing I cant seem to know how to angle the wind to the direction that i want and the force that i want. lets say i want to have the wind hit on the elevation in the x direction and 10 KN/LM. how could i do that?

[@AFMathandEngineering]

@@LEBMG34 not sure where you're from but the code doesn't specify that wind be applied in diagnoal directions, usually only orthogonal directions (x and y) plus eccentricities that produce torsional moments that also must be designed for. Consult your code to see what is required.

[@juanortegam73]

Dear, is it possible to use "Add to existing load" command?

[@AFMathandEngineering]

If you want to add additional loads of the same type yes.

[@poornimakn1523]

Sir can you please upload vedioes on analysis of bubble deck slabs using staad-pro and Etab softwares

[@WinTunDIY]

Thanks a lot

[@AFMathandEngineering]

No problem!

[@jusufvelovic7562]

I added some floors to the building i made, but when i look at the response plots and look at diaphragm drifts those additional floors have 0 drift like the curve just stops once it reached those newly added floors. Do you know why this is happening. I am still a novice at etabs

[@AFMathandEngineering]

It sounds like you may not have defined those new floors as diaphragms. Otherwise those floors would be experiencing some drift.

[@jusufvelovic7562]

thanks for the quick reply it was that!. Im so surprised this was the problem because i would have assumed that the properties of the floors below would go to my newly copied floors that i made similar to the master story. Again thanks for your help!

[@AFMathandEngineering]

No problem, it was good timing! Good luck!

@@joejoe4172 no, haven't looked into it. I would suggest consulting the etabs manual.

[@kencwing]

WHAT IS THE DIFFERENT BETWEEN THIS ONE AND WIND DIAPHRAGM

[@AFMathandEngineering]

I suggest you download the lateral loads manual from CSI on ETABS and review it to find exactly how both are calculated based on your code and where you're from. However, the wind loads applied to cladding as done in this video calculates the lateral loads based on the exposure area that you assign as cladding in the program. Wind loads to diaphragms generates and applies equivalent lateral forces and torsional moments directly to diaphragms defined as rigid. Using a different q value, either for structural or non structural elements may also be required. Which you want to use and in which situation is up to you as a designer. Hope that helps.

[@joejoe4172]

No result was given after I did the analysis.Why?

[@AFMathandEngineering]

That's a bit too general of a question..what do you mean no result?

[@joejoe4172]

After pressing "run analysis", nothing was changed. In your video, your window was changed to "3-D view displacement". But in my case, the window was still "3-D view Wind pressure coefficient".

[@AFMathandEngineering]

@@joejoe4172 That's not really something I can comment on unfortunately, it may be that ETABS has some sort of bug that isn't letting it run, or that it doesn't automatically go to the deformed shape and you need to manually check the results. if the little lock is closed, that means that the model has run. If it isn't you'll have to try to troubleshoot that error yourself. Good luck!
