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.
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
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)
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?
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
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.
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.
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".
@@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!
Hello Sir. Very Interesting Presentation. I like what you did. Please Can You Upload More Videos On design and Analysis of Structures (Story Buildings) Using on this Program Software. I am Learning how to use it in my field work. Please more and More presentation I expect from you. Much Appreciation. Thank You.
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.
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)?
Also, for actual design it's recommended you apply your wind load directly to diaphragms, see our video on this topic here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KHb0mABCofE.html
@@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?
@@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.
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
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!
