摘要
利用有限元分析软件建立了混合梁独塔斜拉桥的空间模型,分析了混合梁独塔斜拉桥在有、无辅助墩情况下的非线性静动力特性的异同,讨论了在有、无辅助墩情况下对混合梁独塔斜拉桥非线性静动力特性的影响,得出了有指导意义的结论。
The paper establishes spatial model of single stayed-cable bridge with composite beam by using finite element analysis software, ana- lyzes similarities and differences of non-linear static and dynamic characteristics of single stayed-cable bridge with composite beam under the con- dition of with and without auxiliary pier, and discusses the impacts of within and without auxiliary pier upon non-linear dynamic and static char- acteristics of single stayed-cable bridge with composite beam, and finally draws some guiding conclusions.
