Eigenvalue Analysis at each time step of Dynamic Analysis

Post by Petroskal » 01 Apr 2019, 14:28

Greetings,

I would like to know if it's possible to run an eigenvalue analysis at each time step of a non-linear time history dynamic analysis. My objective is to know how much do the periods of vibration change during the motion of the building. I am interested only for RC moment resisting frames.

Thank you in advance!

Hello Petroskal,
In SeismoStruct v2018 this is not possible. However, we have already programmed this feature in v2020, which will be available in the autumn of 2019.

Thank you for your answer.

Could it just run an eigenvalue analysis only in the end of the dynamic analysis, using the final state of the building model?
