连续梁桥桥墩横向地震力简化计算方法探讨

Discussion for Simplified Calculation Method of Seismic Load to Piers of Continuous Bridges

基于对连续梁桥中产生横桥向地震力的控制因素进行分析,提出一种基于反应谱理论的连续梁桥横桥向桥墩地震力简化计算法,并采用算例验证了其精确性和适用性。结果表明该方法能适用于普通的连续梁桥,在较小的计算量下,其计算精度可基本满足工程应用的需求。

A simplified calculation method of seismic load to pier of continuous bridge, basd on the response spectrum theory, is given in this paper through key parameter analysis of lateral seismic load in continuous bridges. The examples show that the method can be used in normal continuous bridges and have enough precision for actual project with comparatively less amount of calculation.
