郑州大学西亚斯国际学院篮球馆封闭组合张拉膜结构分析

Analysis of tension membrane structure with enclosed combination for the Basketball Gymnasium of Sias International College

以郑州大学西亚斯国际学院篮球馆为研究对象,应用有限元程序Ansys对其封闭组合膜结构体系进行了找形分析,借助支座提升和温度作用对膜施加初始预应力得到预求的膜结构形状.其形状满足建筑初步设计造型的要求,且膜上的应力分布比较均匀.随后又对成型后的膜结构体系进行了设计荷载下的静力分析,采用极限状态设计方法,选取了由自重、雪荷载和风荷载组合而成的四种工况.经分析计算,雪荷载和风荷载参与的工况组合对结构的影响较大,本文主要给出这两种情况下的结构反应.从而探讨了膜结构体系的受力和变形规律,为类似工程提供参考.

The form-finding analysis of the membrane structure with enclosed combination for the Basketball Gymnasium of Sias International College is conducted by the finite element program Ansys.By means of support rise and temperature effect,initial pre-stress is introduced into the membrane and the desired shape of membrane structure which satisfies the requirement of initial building design with evenly distribute stress is obtained.In addition,a static behavior under design load for the membrane structural system...
