Under the environment of the finite element analysis software ANSYS,the paper undertakes the displacement analysis of the joints over the bridge of some steel truss bridge under the static effect by establishing the finite element models,analyzes the earthquake loading response by putting the earthquake spectrum at the bridge side,and achieves some conclusions.%在有限元分析软件ANSYS环境下,对建立的有限元模型某钢桁架桥的桥体在静力的作用下进行节点的位移分析。同时,在该桥体侧向施加地震谱,分析该结构的地震荷载响应,并得出一些结论。
