摘要
通过建立某斜拉式桁架桥节点的ANSYS有限元模型,并根据结构的实际情况对边界以及荷载进行模拟,分别计算出节点在恒载以及恒载加活载作用下的应力分布情况,这一分析方法和结果可为局部应力分析以及同类型桥梁的设计提供参考。
An ANSYS finite element model is established against node of one inclined truss bri- dge and the border as well as the load are simulated. Meanwhile the stress distributions are calculated at the condition of dead load and changing load on the basis of dead load. This analysis method and resuhs can provide reference for local stress analysis and the design of the same type of bridge.
