摘要
利用有限元分析软件ANSYS对某工程的大跨度型钢混凝土桁架转换层节点进行了实体非线性数值模拟,得到了按整体模型逐层顺序分析所得节点处各构件内力作用下型钢混凝土节点的应力分布和变形性能。施工阶段对节点的监控结果表明,现场实测结果与非线性条件下数值模拟分析结果吻合较好,可为此类构件的节点设计及其性能分析提供理论参考。
This paper analyzes the steel reinforced concrete large span transfer truss joints using the finite element analysis software ANSYS,and get the joints deformation and the mechanics increase,such as deformation properties,stress distribution.The monitoring results during construction phase show that nonlinear numerical simulation analysis,which is in good agreement with the test results,is an effective method for the mechanical property analysis on this kind of structural components.
