Nonlinear Time history Analysis in ETABS Software v20

[@sobrevigaezekeilkeizen8096]

Hello Engr may I ask a question, I saw when you run the analysis there is 1 error which is " NON-ZERO TIME-HISTORY FUNCTION VALUES WILL BE IGNORED AT START OF LOAD CASE." it is approved your design even if you have an error like that? thank you for your response and willing to join.

Sir. Could you please make a video on how to conduct a nonlinear time history analysis in Sap2000 software for steel structure

[@KSSE_Engineer]

Noted keep tune

Hello, sir. I have a trouble when i input my time history function but the function graph just a line without acceleration appear. Can you help me with this? What should i do? Thank you!

[@KSSE_Engineer]

Hi dear, you can check your input carefully like the video. If you wore unable then please join the channel membership I will solve your problem personally.

[@chocohazelnuttt]

@@KSSE_Engineer thank you for the response! I will join the membership as soon as possible, but also ive already sent you an email with some images. Maybe you can check on it.

You have to check your time history station file (.txt) and Put the time interval between two points correctly which was may be written on your .txt file.

hello sir, is it possible to perform Time history analysis on Stiffened steel plate shear wall on Etabs. Steel plate shear wall not concrete.

[@KSSE_Engineer]

Yes .

Error in assigning hinges. Requested calculated properties may not be available for materials or section types. Above error is showing when i am applying hinges. Will you please help me out to solve this issues.

[@KSSE_Engineer]

Please follow the video carefully you won’t get error.

[@jurnalisnh8094]

hello sir, may i ask, why i cant open hinge result after the analysis, i'm following ur step so far and it happen

[@KSSE_Engineer]

Maybe you forgot to check the nonlinear analysis from the load cases

@@KSSE_Engineer sorry to bother, im choosing the Linear Modal, is it the cause? so i need to change it to Nonlinear Modal(FNA)

[@user-zs9zl5in5e]

Aos sir. Sir The results of acceleration and base shear are not coming for steel plate shear wall. After fast non linear analysis. Can you plz tell us why?

[@KSSE_Engineer]

W salam , maybe the analysis not converged. So I recommend you to conduct a linear analysis first and then do the nonlinear after the analysis completed see the analysis message.

@@KSSE_Engineer i got analysis message but results are not compatible after applying Steel plate shear wall. i have seen your all videos, i am making some mistake. you help guide us alo.t

Sir after nonlinear time history analysis my displacement results shows very less and other results also. Dont understand where is the problem

[@KSSE_Engineer]

You can scale the earthquake recode .

I am trying to do a nonlinear fna but when I assign hinges, there is no hinge results after running it,what could be the problem?

[@KSSE_Engineer]

You should assign an overwrite hinge from Assign .

[@abuamir3172]

Sir When I did the analysis the sap software gives me the sentence " error in reading time history file" so How can I solve this problem.

[@KSSE_Engineer]

What is the error? Maybe you define wrong the step time , skip points and others . You can check my channel there is more videos how to conduct time history analyses.
