摘要
介绍了现行桥梁抗震计算分析的几个方法.确定性方法中的弹性静力法,静力弹塑性分析,反应谱法,时程分析法;概率性抗震分析方法中的随机振动虚拟激励法.并对各个方法的优缺点加以说明,着重介绍了随机振动虚拟激励的基本原理和特点.最后提出了有待进一步研究的几个问题.
This paper summarizes computer method of seismic analysis for bridges. Confirmable method includes： elasticity static method, static-plastic analysis, response spectrum method and time history scheme; Seismic analysis of probability includes： the random vibration and the pseudo excitations method. This paper discuss the virtue and defect about these methods. The keystone and trait of the pseudo excitations method are paticularly presented. At last we bring forward some questions needing further study.
