Dear support team
I'm so sorry for typing mistake, I meant I'm modelling a 3D concrete frame. I applied two orthogonal acceleration time histories in X and Y direction. I wanted to know if I applied record just in one direction for a 3D model would it yield to wrong results?
and if I take effective ...

2 distinct cases:
in first case maximum story drift is selected as DM (Damage Measure) and Spectarl acceleration of the first mode for 5% damping ratio is selected as IM (Intensity Measure). in the second case DM is the same as previous case but PGA is selected as IM. the input motion is Landers ...

Dear support team
I model a 2D concrete frame. i want to obtain DM-IM curve for X direction. I assign time history acceleration to base nodes in X direction, should I assign the same acceleration in Y direction too?
Best regards

thanks a lot dear Huffte

Dear support team
I run a single record IDA analysis scaled from 0.5g to 3g and 0.5g step increment. After completion of analysis when I try to see post-processor results for last 3 steps I get this error message: "integer flow" where is the source of that error?
2nd question: Is it possible to run ...

Your continuous support is appreciated

- I model a simple 2D (1 bay 1 story) frame and use adaptive static pushover analysis. restraining all DOFs in supports and also all DOFs but x direction for upper nodes. I get this error message when i click Run tab: "Unable to apply the entire phase load. Phase terminated". Assigning a rigid link ...

Dear support team
is there any example file of adaptive static pushover analysis available?
Best regards

Thanks for your help, I have read the manuals and related articles on the internet, in running pushover analyses by SAP2000 or Etabs you do not have to specify incremental nodal loads(just defining lateral load pattern and the software distributes them automatically). but in Seismostruct you define ...

Hi there
assuming I have chosen force type Incremental load, how is the value of incremental load determined? And how should I calculate value of displacement if displacement method is selected?
how is the base nominal shear calculated?
in example ch2-12 (eigenvalue analysis example) there is a ...
