摘要: 以实际工程为背景，采用非线性有限元法对索穹顶施工过程进行了逆向模拟分析，通过改变索长实现结构的整体提升，索长改变通过施加温度荷载实现。在ANSYS中建立了索穹顶的索杆梁有限元模型，主动索和辅助索为2节点索单元即link10单元，被动索采用多段的link10单元来模拟，撑杆为link8单元，内环梁为beam4单元。利用ANSYS中强大的APDL编程功能开发了索穹顶结构施工过程逆向模拟分析程序，为整体提升技术在大跨度索穹顶结构中的应用提供了有益的参考。Abstract: Based on the practical projects, adopting the nonlinear finite element method, the construction process of cable dome was analyzed.The integral lifting process of the structure was realized through changing the length of the cables and the temperature could simulate the variations of the cable length.Based on the ANSYS, the cable strut beam finite element model was established, and the positive constant force cables and the subsidiary cables, the passive cables and the mast were simulated with the two node curved element(link10 element), multistage link10 element, the link8 element and the beam4 element respectively.By the ANSYS powerful APDL programming function, the development program of cable dome structure construction process inverse simulation was made.Helpful reference was offered for the application of integral lifting in large-span cable dome.
