摘　　要：应用有限元程序AN SY S对黄河水利职业技术学院新校区风雨操场膜结构进行了找形分析,确定了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.通过本工程刚柔性组合边界张拉膜结构的找形分析,探索了刚柔性组合边界膜结构进行找形分析时索和膜预应力取值、支座提升、找形分析收敛准则等一系列问题,为类似工程提供了参考.This paper conducts the form-finding analysis of the membrane structure for gymnasium of the new campus of Yellow River Hydrotechnical Vocational Institute(YRHVI) by Ansys.The membrane shape which is realized meets the shape of initial architectural design and the stress in the membrane are evenly distributed.During the form-finding analysis of this membrane structure with rigid-flexible combined boundary,some problems,such as the prestress optimization of cable and membranes,pedestal shifting,convergent criterion are discussed,which provides reference for similar engineering.
