Modal Time History Analysis

Post by aafshari » Sat Oct 07, 2023 1:47 am

In OpenSees, how can I perform modal time history analysis to obtain the response of each structural mode separately from the software output? I mean, is there any way to obtain the response of the structure for each mode separately?

No, OpenSees does not perform modal time history analysis. You have to post-process to get the modal response.

Thanks a lot. Can you explain what kind of post-process do you mean? I think I should have pre-process.
