DEVELOPMENT OF HIGH DUCTILITY LOW YIELD POINT STRENGTH STEEL SHEAR PANEL DAMPER

Low yield point strength steel 100 (LYP100) was widely applied to the metallic shear panel damper. To develop function separate damper with LYP100，panel shapes，links of the frame fixture and vertical ribs which a ffect the deformation capacity of the damper were investigated by static cyclic loading tests The test results show that the deformation capacity can be improved greatly by alleviating the stress concentration locating at the panel comers. The largest mean shear strain 70% was achieved by optimizing the parameters
