Dynamic Energy of Building under Earthquake Excitation Based on FEM

Abstract:

Article Preview

Evaluation on dynamic energy characteristics of building under earthquake excitation with passive friction damper-protected devices based on finite element method (FEM) is actively carried out in this study. The mechanical model of the 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 results indicate that the earthquake-induced vibration of the building can be substantially suppressed and the proposed energy evaluation criteria can be effectively utilized in the examination on seismic mitigation performance.
