摘　　要：仿生结构是通过观察自然界的生态形式与规律,结合现代技术创造的结构体系。第十届中国花卉博览会主入口大门主结构采用的结构仿生形式是类似树叶叶脉的交叉网状支撑组织结构,表皮采用了覆盖膜结构。对仿生结构在入口大门中的实现做了重点论述,在基于逆吊法结构找形技术及基于拓扑优化杆件布置技术基础上,通过研究与分析确定出最适合的结构形态和杆件布置,并对此结构体系进行了详尽的计算与分析。分析表明,按照仿生结构形成的结构体系,具备良好的建筑形态和结构力学性能。Bionic structure is a structural system created by observing the ecological form and law of nature and combining with modern technology.The bionic structure of the main entrance gate of the 10th China Flower Expo is a cross-mesh support structure similar to the leaf veins,and the skin adopts a covering membrane structure.The realization of the bionic structure in the entrance gate was emphatically discussed,based on the form finding technology of the inverse hanging method and the topology optimization of the layout of the bar,the most suitable structure shape and layout of the bar were determined through research and analysis,and the structural system was calculated and analyzed in detail.The analysis shows that the structure system formed according to the bionic structure has good architectural form and structural mechanical properties.
