periods for bidirectional pushover analysis

Post by ccasotto »

Hi,

I am modelling a simple 3D structure, 1 storey, 2 bays in one direction and 3 in the perpendicular direction, and I am running a pushover analysis in the two directions simultaneously.
I would like to get the periods of the structure at every step of the pushover analysis, but the results I got have no sense.
I tried to do it running the pushover only in one direction, and it gave me reasonable periods increasing as the structure got more and more damaged during the pushover.

Do you have any solution for this problem?
Thanks
Chiara
