Hi All,
Please if someone can guide me how to claculate the overall structural damping after doing the pushover analysis in etabs using linear frictional dampers. I have a case in which i am designing the dampers. I am defining the forces etc in the etabs regardless of initial damping to get the required response of the structure in after the ULS seismic event. NOw the question is to calculate back the damping generated by the system using the link properties i defined. Just any start up hint would be great. thanks.
Regards,
