Abstract

In order to study the influences of viscous dampers on the seismic resilience of RC frame structure, the seismic resilience assessment of RC frame structure with viscous damper was carried out based on the incremental dynamic time history analysis method. Combined with FEMA P-58 and Chinese seismic resilience assessment standards, the repair cost, repair time curve and fragility information of the main damaged components are corrected accordingly, also compare and analyze the main seismic resilience indicators such as repair cost, repair time, and personnel casualties of uncontrolled structures (UCS) with controlled structures (CS) to clarified the influences of viscous damper on the seismic resilience of RC frame structure. The results show that setting up viscous dampers properly in RC frame structure can not only reduce the seismic response of the structure, lower the probability of structural failure, but also effectively improve the seismic resilience of the structure.
