摘要
以某独塔空间双索面混合梁(由结合梁与混凝土梁组成)斜拉桥为工程背景,对该桥的动力特性进行分析。基于有限单元法理论,确定了该桥的空间计算模型,在此基础上应用反应谱法研究了该桥的抗震性能。
Taking a single-pylon double-plane composite beam(composed of combined beams and concrete beams) cable-stayed bridge as the engineering background,the article analyzes the dynamic characteristics of this bridge.Based on the theory of the finite element method,the article determines the space calculation model of this bridge,and on this basis,studies the seismic performance of this bridge by the application of response spectrum method.
