张弦立体桁架支撑的带飞杆的膜结构集膜结构、飞杆与张弦立体桁架等多种受力特性于一身.给出了带飞杆的膜结构找形分析时在ANSYS上的实现过程和关键处理,并以青海省西宁市亲水中心大厅屋盖为案例进行了找形.结果表明,找形形状接近建筑初步设计造型的要求,且膜上的应力分布比较均匀.通过提升后与最终找形飞杆顶端节点的竖向坐标值对比,证实了带飞杆的膜结构找形时必须和弹性构件一起联合找形.张弦立体桁架支撑的带飞杆的膜结构找形分析时可不考虑结构自重,但需要考虑张弦立体桁架支撑的协同作用.

The membrane structure with flying rod supported by the tensile string three-dimensional truss integrates a variety of force characteristics such as membrane structure, flying rod and tensile string three-dimensional truss. The implementation process and key processing of the form-finding analysis of membrane structures with flying rods on ANSYS are given, and the hall roof of the water center in Xining, Qinghai Province is used as a case to find forming. The results show that the shape-finding shape is close to the requirements of the preliminary design modeling of the building, and the stress distribution on the membrane is relatively uniform. By comparing the vertical coordinate values of the top node of the final shape-finding flyrod after lifting, it is confirmed that the membrane structure with flying rod must be jointly form-finding with the elastic member when looking for form. The morphogenic analysis of the membrane structure with flying rod supported by the tensile string three-dimensional truss can not consider the self-weight of the structure, but the synergistic effect of the tensile string three-dimensional truss support needs to be considered.
