Earthquake Response Characteristics of Bridges Under Multiple-Support Excitations

这个项目处理的问题是差分（相）地震动对桥梁结构响应的影响。考虑了多支撑激励。使用密集仪器阵列和合成地面运动的记录。重点放在动力分析的随机方法上。本研究结果有望对实践产生实际影响：将其纳入地震分析计算机程序，如SEISAB和桥梁地震分析和设计的一般指南。这是普林斯顿大学发起的一个持续两年的项目的第二年研究。

This project deals with the problems of the effects of differential (phased) ground motion to the response of bridge structures. Multiple- support excitation is considered. Records from dense instrument arrays and synthetic ground motions are used. Emphasis is placed on the stochastic method of dynamic analysis. The results of this research is expected to have practical impact on the practice: to be incorporated in the seismic analysis computer programs such as SEISAB and the general guidelines for the seismic analysis and design of bridges. This is the second-year research of a 2-year continuing project originally initiated at the Princeton University.
