REQUIRED SEISMIC DEMAND OF SHEAR PANEL DAMPERS APPPLIED IN STEEL STRUCTURES
The target of the present study is to analytically investigate the demand on shear panel dampers (SPDs) installed in steel framed structures under 3 kinds of design earthquake motions, to serve as guidance for the recommended capacity of SPDs in seismic design. For this purpose, an extensive dynamic analysis is carried out on steel structures with SPD devices under strong earthquake motions. The type of SPD considered consists of stiffened steel shear panels which can be designed to vary on different dimensional and mechanical parameters. To describe the restoring force characteristics of such steel SPDs, the analysis uses a newly developed combined hardening model based on experimental data. The demands made on SPD devices in various kinds of earthquake conditions are examined, and the analytical results are then summarized to give recommended values for determining the necessary deformation capacity of SPDs.
