Effect of Width-to-Thickness Ratio on Large Deformation in Shear Panel Hysteresis Damper Using Low Yield Point Steel

Abstract:

Recently, building and other civil engineering structures are built with energy dissipating device in order to reduce the damages caused by earthquake. There are a number of seismic energy dissipating device and steel dampers are among many energy dissipation device which is widely used because they are easy for construction, maintenance and low cost. Shear panel damper (SPD) is a type steel damper that dissipates energy by metallic deformation or using hysteresis of material as a source of energy dissipation. Low yield point steel is a good material to be used as a hysteresis damper since it has excellent ductility performance. Nonlinear finite element analysis was carried out to predict the large deformation and hysteretic behavior of SPD using low yield point steel (SLY120) for different width-to-thickness ratio. In order to verify the analysis simulation, quasi-static loading was also conducted and from the comparison a satisfactory result was found.
