Open publisher page 2 citations

Abstract

Seismic performance of the SDOD and MDOF structures incorporating two types of frictional dampers and viscous damper are studied by using time history analysis method. The analysis results show that all three types of dampers can control response of structure efficiently, and T-shaped core plate frictional dampers(TFDs) possess better displacement control effects than pseudo-viscous frictional dampers(PVFDs), but, PVFDs have better acceleration control effects than TFDs.
