Hi

 

Harmonic analysis is a linear type, hence we can not include nonlinearities such as material nonlinearities.

 

You can use a full transient analysis imposing a transient earthquake load/accel., and then also have and use nonlinear material, and look at plasticity (e.g., plastic strains).

 

All the best

 

Erik
