内容記述
The main structural damage occurring in high-rise steel buildings subjected to long-period ground motions is cumulative inelastic deformation concentrated in the beam-column connections. The seismic performance of such buildings is thus significantly influenced by the type of beam-column connection detail. However, there is no current statistical information relating to beam-column connection details of existing high-rise steel buildings. Therefore, in order to evaluate seismic demands, a series of dynamic response analyses and long-period ground motions are conducted using two prototype building models. In addition, the effective distribution of dampers is considered in relation to retrofitting by steel dampers.
