MODELING CONSIDERATIONS OF FRICTION DAMPER ASSEMBLY FOR SEISMIC ANALYSIS
Earlier literature used elasto-plastic model for numerical modeling of friction dampers. However, the friction phenomenon is velocity dependent and elasto-plastic model is displacement dependent. Hence, their equivalence is not obvious and not established based on a systematic study. The present study evaluates three modeling approaches for friction dampers – (a) rigidly connected damper (b) friction…
