What I mean for Sa of T1 5% is the first-mode spectral acceleration with 5% damping coefficient. This is the vertical axis (as the Intensity Measure where other researchers use PGA instead of Sa,T1 of 5%) plotted against the horizontal axis of maximum interstory drift (Demand Measure, DM) for a typi...

Thank you for the response Admin. What I mean is from the results of post-processing->IDA Envelop->Max Drift vs. Corres. Base Shear, how can I make my IDA curves (Sa of T1 5% vs. Max. ISD Ratio)? Thank you again for your further reply. By the way, I know that the video I posted was not created by Se...

Hi, I'm working on IDA using Seismostruct. I found a video on how to use IDA in Seismostruct. However, I do not know how to interpret the post-processing values and what are the needed data from Seismostruct for IDA curves.

Here's the sample video I found:
