摘　　要：第七届中国花卉博览会花伞结构根据仿生结构设计。结合具体的结构设计,介绍了花伞的结构体系,结构静力、动力分析结果,并根据结果确定合理的混凝土浇筑高度,重点介绍了结构多杆件交叉连接的处理方法,并对复杂节点进行有限元分析。通过对花伞进行静力弹塑性分析,验证了结构性能可以满足规范要求。The structural design of the flower umbrella in the 7th China Flower Expo is made with bionic construction.The structural characteristics of the project were described.The static and dynamic analysis of the structure were given,based on the results of which,a reasonable concrete pouring height was determined.The structure of multi rod cross connection processing method was focused and finite element analysis for the complex node was done.Through the static elasto-plastic analysis on the flower umbrella,it verifies the structural properties can meet the requirements of corresponding code.
