Abstract

Abstract

It is explored that the effect of varying the damping ratio and stiffness of engineering structure on earthquakeaction. The analytic result shows that the increased damping ratio can effectively reduce the structural dynamic response. Theenhanced stiffness can mitigate the structural displacement response. But it can not effectively control the structuralacceleration response. Based on the analysis and conclusion of the recent research results, and then combined with theseismic code, the modified formula for seismic coefficient of engineering structure using the viscoelastic damper is given atlast.
- engineering structure,
- viscoelastic damper,
- mitigation earthquake,
- seismic coefficient
