| 摘 要： | 应用有限元程序ANSYS对郑州大学西亚斯国际学院篮球馆组合屋面膜结构进行找形分析,确定满足建筑初步设计造型要求的膜的形状,且膜上的应力分布比较均匀。通过对封闭式组合屋面膜结构的找形分析,探讨此类膜结构找形过程中单元划分、边界处理、弹性模量取值等处理方法,提高找形效率。在考虑支承体系对找形结果影响的基础上,进行协同找形分析,对比说明协同找形分析的必要性。

| Abstract: | The form-finding analysis of the basketball gymnasium combined-roof membrane structure for SIAS International College of Zhengzhou University is conducted by ANSYS.The membrane shape which meets the shape of initial architectural design is determined and the stress in the membrane is evenly distributed.With the form-finding analysis of this close combined-roof membrane structure, the problems in the form-finding processes such as division of element,boundary condition treatments and value adoption of elastic modulus is approached which improves the form-finding efficiency.At last,the coordinated form-finding analysis between cable membrane and steel truss support system is studied,which puts forward the necessity of coordinated form-finding analysis. |
