Hi Seismosoft

Thank you so much.

Dear Rui

Current response curves in SeismoStruct may use to define viscous dampers based on approximate simplified methods but for exact(and realstic) hysteretic curves need to velocity dependent hysteretic curves.

Damper exact response is needed in some research(not overall structural response ...

Dear Rui
No, because viscous damper force is dependent on velocity.

F = CV^alpha
F = viscous damper force
C = damping constant
V = velocity
alpha = velocity exponent

Dear Rui

Thank you for your suggestion.I read some experimental results and i believe that "plst link" can not adequate for FPS modeling verification, beacuse "plst link" application is based on a simplified modeling method(not accurate) and it does not consider friction coefficient variations with ...

Hi,
Are friction pendulum isolator modeling results by plst link with experimental works have been verified?
