Abstract

Low-yield-strength steel shear panel damper (LYSPD) is widely applied to the seismic system by the large plastic deformation capacity and the damping function. It is designed to dissipate the energy result from earthquake or shocking and keep the main structure intact. Although there are several types of dampers made from low-yield-strength steel (LYS) in the world, the ultra large plastic deformation mechanism (ULPM) is not attached importance on by the past researches. Therefore, in order to clarify the ULPM, both the finite element method and the experimental method are conducted for gaining the strain distribution of the LYSPD. The research results show that the ULPM maybe affected by the interlaminar deformation.
