2008奥运羽毛球热身馆单层网壳稳定分析的ANSYS二次开发及其应用
SECONDARY DEVELOPMENT OF ANSYS SOFTWARE AND ITS APPLICATION IN SINGLE-LAYER RETICULATE SHELL OF BADMINTON ARENA FOR 2008 OLYMPIC GAMES
【摘要】 针对ANSYS中Beam188单元,通过程序二次开发解决了大规模单元端部释放问题,建立钢结构网壳ANSYS分析模型,进行了非线性屈曲分析,得出了在大跨度钢结构网壳设计中,采用Beam188单元能够得到真实的模拟效果。
【Abstract】 ANSYS is powerful finite element analysis software.To Beam 188 element in ANSYS,a fundamental procedure based on APDL programming technique to solve the problem of element endrelease is presented.Then a model of steel structure lattice shell is established and the non-linearity stable analysis is also done.Finally,an authentic simulated result is gained.
