Hi,

You can use recorder reaction command for base nodes and recorder displacement for the top node or nodes. Then you should sum data from all base nodes at each step and plot sum column against the top node displacement column.

Good Luck.

Thanku so much

I think it is better to write some script (for example in MATLAB) to read output files and plot the pushover curve. Therefore, you do not need to copy and paste the results in Excel each time you perform an analysis. Also, you can call OpenSees from MATLAB and perform post-processing after the analysis is complete. Use this command line in MATLAB to do so for your case:

!OpenSees.exe Rcframepushover.tcl.tcl

thanku so much Egemen Sönmez sir for your help
