Abstract：The damping performance curve is used to adjust the seismic response when the damping ratio is different from the inherent damping ratio of the structure. It is of great significance to the simplified design and analysis of the damping structure. This paper first derives the analytical expressions for the displacement damping rate ηd and acceleration damping rate ηa of the single-particle system under harmonic excitation, then classifies a large number of seismic waves based on the characteristic period, and conducts time history analysis of all different types of seismic waves , To draw the damping performance curve that can be used for seismic waves in various sites. Through elastic time history analysis of a large number of seismic wave records classified by site and statistical and non-linear regression analysis of the results, the parameter of excitation period Tg is added into the consideration range, so as to determine the calculation of the seismic wave under the elastic time history. Fitting formula of displacement and acceleration damping rate. A damage performance curve considering the nonlinear state of the structure is established. The analysis shows that although increasing the damping ratio can reduce the plasticity of the structure, the reduction effect is limited. The greater the plasticity, the less obvious the damping effect of increasing the damping ratio. The research in this paper expands the application range of the damping performance curve and provides an important basis for the performance-based design of damping structures.
Keywords: performance curve, shock absorption rate, site category, seismic wave, time history analysis
