采用ANSYS软件对成都双流国际机场T2航站楼钢结构屋盖相贯节点进行了分析,通过与真实试验的对比验证了数值分析方法,确立边界条件及网格划分精度,进而对节点的力学性能进行模拟分析,通过计算节点轴向力与轴向位移的关系曲线,评价节点刚度是否与杆件的轴向刚度相匹配;在广泛的文献调研的基础上,确定了极限承载力评判标准及方法,并最终得到节点的承载力及骨架曲线,对节点的力学性能进行了评判。
ANSYS software was used to analyze the steel roof joint of Chengdu Shuangliu International Airport T2 Terminal. The numerical analysis method was verified by comparison with the real test, and the boundary conditions and the meshing accuracy were established. Then the mechanical properties of the joints The simulation analysis is carried out. By calculating the relationship between the axial force and the axial displacement of the joint, the stiffness of the joint is evaluated as to whether the stiffness of the joint matches the axial rigidity of the rod. Based on the extensive literature survey, the evaluation criteria and methods of the ultimate bearing capacity , And finally get the bearing capacity of the node and the skeleton curve, the mechanical properties of the node were judged.
