Energy Properties of Building Structures Subjected to Strong Earthquake

Abstract:

The evaluation on energy characteristics of earthquake-excited building structures with seismic protection devices is actively carried out in this study. The mechanical model of passive friction dampers is first introduced and the dynamic model of building-damper system is proposed. The evaluation criteria of energy responses are developed and applied to the earthquake response mitigation of a real multi-story building incorporated with friction dampers. The observations indicate that the earthquake-induced vibration of the structure can be substantially suppressed and the proposed energy evaluation criteria can be effectively utilized in the examination on seismic mitigation performance.
