| 摘 要： | 独塔斜拉桥是由塔、梁、墩和索构成的一种组合体系桥梁,结构形式较为复杂。文章以广西南宁白沙大桥为工程背景建立了基于ANSYS的三维有限元分析模型,对其自振特性进行理论分析,并将计算结果与环境随机振动法的测试结果进行比较,说明所采用的有限元模型能够较好地模拟桥梁结构的实际状况,同时也说明大桥在运营状态下的动力特性符合要求。

| Abstract: | The main component parts of single pylon cable-stayed bridge are the main tower,beam,cable and pier.Taking Baisha bridge in Nanning of Guangxi for the engineering background,this paper established 3d finite element analysis model based on ANSYS for the natural vibration characteristics analysis.By comparing the theoretical calculated results with the test results of environmental random vibration method,the conclusion shows that the finite element analysis method adopted by this paper can better simulated a... |
