| 摘 要： | 根据我国现行抗震规范（GB50011—2001）的反应谱曲线，对Clough—Penzien模型的参数取值进行了具体研究。采用时间包络函数考虑地震动的非平稳性，根据加速度峰值等效原则确定了谱强度因子S0的表达式，表明谱强因子不仅与地面加速度特性、场地类别有关，而且与结构的动力特性（阻尼比、自振周期）有关。最后对谱强度因子计算做了简化处理，为随机抗震计算分析提供了参考依据。

| Abstract: | A study on the parameters of Clough-Penzien seismic random model based on the response spectrum in the GB50011-2001 is carried out.The non-stationary nature of the ground motion is considered by the envelope function.It is found that S0 can be determined by the equivalence principle of peak ground acceleration.The results show that S0 is not only related to ground acceleration and site condition but also to structural dynamic property(damping ratio,natural vibration period)as well.Ultimately,a simplified method for calculating S0 is carried out.The parameters given in this study provide a theoretical fundamental for stochastic seismic response analysis of structures. |
