［摘要］针对海口融创观光塔高耸钢结构项目，考虑到高耸钢结构自重轻、刚度小的特点，提出并分析了实现该仿生塔的两种结构方案。方案一的主体结构由钢管柱、环形桁架和钢梁组成；方案二的主体结构采用交叉网格结构组成。详细介绍了两种结构设计方案的设计思路、计算分析过程和具体的计算结果，并对两种方案的利弊进行了对比分析。经过对比分析，最终确定方案一性价比更高。

Abstract: Aiming at the high-rise steel structure project of Haikou Rongchuang Sightseeing Tower, considering the characteristics of light weight and low stiffness of high-rise steel structure, two structural schemes had been put and forwarded to realize the bionic tower. In scheme one, the main structure was composed of steel pipe column, ring truss and steel beam. In scheme two, the main structure was composed of cross grid structure. The design ideas, calculation and analysis process and specific calculation results of the two structural design schemes in detail were introduced, and the advantages and disadvantages of the two schemes were compared and analyzed. Through comparison and analysis, scheme one was determined to be more cost-effective.  

Keywords:Haikou Rongchuang Sightseeing Tower； bionic tower； ring truss； cross grid； overall stiffness
