摘要
襄阳科技馆钢结构屋盖采用空间交叉网格体系,节点形式复杂。本文采用ANSYS进行了考虑几何非线性和材料非线性的关键节点的数值模拟分析,验算其抗震承载力并确定节点的薄弱部位,同时提出加强措施并进行有限元分析验证,为相似节点提供参考。
The steel roof structure of Xiangyang Science and Technology Museum is spatial cross-grid system.The joints are complex.ANSYS was used for the joints finite element analysis which taking both the geometric nonlinearity and material nonlinearity into account.The analysis above checks the seismic resistant capacity and finds the weak parts of the joints.At the same time,the strengthening measures are proposed and verified by finite element analysis,which can provide reference for similar joints.
