displacement & drift

[abbas62]

I have a 3d model pushover and time history . I want compare the drift and displacement but i dont know What steps should be considered.
please help me.

Dear abbas62,

We are not sure we can fully understand your question, but it seems to us that your doubts are more of a general earthquake engineering nature, rather than related to SeismoStruct modelling issues.

Hi
i have steel 2D Frame. How can i get maximum story drift ratio of each Story in IDA method. i need Incremental dynamic analysis response plot of spectral acceleration versus maximum story drift ratio.

You can certainly get a time history response of drift by specifying the appropriate nodes and checking the "relative displacement" box in the "global response parameters" section of the post-processor. You may also plot a time history of chord rotation in the "frame deformations" section of the post processor if you have not discretized the elements in question.
