hELLO eVERYbODY,
I was wondering
, if it is possible to record time period(s) (1st mode, 2nd mode) during the non linear time history analysis of structure.
I would love
to know how the time period of my structure changes due to yielding at various location
Take Carez,

sure, in the examples, the time-history analysis is done one step at a time. you can put in the eigen command at the end of each step (or every Nsteps to not slow things down too much)
