Re: Modal Analysis + Mass Partiticipation Factors
Hello
I wanted to know if modal and response spectrum analysis is added to the recent version of opensees ?

Re: Modal Analysis + Mass Partiticipation Factors
Yes, they are already in the official opensees

I am trying to run the example of response spectrum available on https://opensees.github.io/OpenSeesDocu ... ctrum.html, in tcl, however it is giving an error of invalid command as shown in the figure.

Re: Modal Analysis + Mass Partiticipation Factors
Just change the "responseSpectrum" command with "responseSpectrumAnalysis".
We recently changed the name and updated the documentation. However the official documentation still has to be re-compiled

Re: Modal Analysis + Mass Partiticipation Factors
Thank you for the reply
Understood.
I am currently trying to do response spectrum analysis for 4 storey building to understand the output and trying to record accelerations. Currently using the same response spectrum from the example, the acceleration recorded for every mode is same.
The following snap shows the model along with time period of each mode and recorded acceleration and commands used for recording.
How should be acceleration recorded, the above recording commands seems to be not working ?

Re: Modal Analysis + Mass Partiticipation Factors
Response spectrum is not a real transient analysis. You cannot record accelerations as in a transient analysis
