Abstract

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, stiffeners and vertical ribs which affect 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 corners. The largest mean shear strain 70% was achieved by optimizing the parameters.
