Abstract: 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.

Keywords: flower umbrella; static analysis; dynamic analysis; static elasto-plastic analysis
