Earthquake response reduction of buildings by rocking structural systems

摘要

The rocking systems that cause rocking vibration under appropriate control during earthquakes are now under development. One of these systems has weak base plates at the bottom of each steel column of the first story. When the weak base plates yield during a strong earthquake, rocking vibration is caused in the building. This paper examines the effects of rocking vibration with base plate yielding on seismic response of rocking structural systems. The rocking systems with weak base plates can reduce earthquake responses of building structures by causing rocking vibration, based on nonlinear time history analyses.
