滞回型装置减震桥梁的随机反应分析

Stochastic Response Analysis for Bridges with Hysteretic Type Aseismic Devices

应用随机等效线性化方法分析带非线性滞回减震装置的桥梁地震反应 ,以地面加速度为平稳高斯过程作随机谱分析 ;此方法足够精确 ,相对确定性分析法更便于对减震装置作参数分析及设计 ,且该方法可以推广于非平稳反应计算。

The stochastic equivalent linearization technique is applied to analyze the earthquake response of bridges with aseismic devices.The seismic acceleration is schematized through a Gaussian stationary random process,but this method can be extended to non-stationary response.This method is proved to be enough accurate and better than deterministic analysis for parameter analysis and design.
