[摘要] 湖州太湖明珠酒店是由两个对称塔楼通过连接体形成的巨大环形结构，单塔采用钢框架一混凝土核心筒结构体系，连接体采用双向钢桁架转换体系。采用ETABS三维计算软件对太湖明珠酒店的结构方案进行了分析，得出在这种结构体系下，核心筒剪力墙承担了在各种工况下的几乎全部的水平剪力，且墙体配筋率在规范允许范围之内；钢框架结构主要应力比控制在0.75之内；各种总体控制指标均满足现行规范；同时对双向转换桁架、空间曲线钢柱的主要受力性能做了定性的阐述。

Abstract: The Taihu Mingzhu hotel is a super ring structure which is made up by two high-rise steel frame-core systems building contacting by a two-way steel truss. The paper expatiated on scheme analyzing and computing of the Hotel by ETABS, and reached some conclusions. The Shear-wall of core-system bears almost all horizontal shears and the reinforced ratio of shear-wall is within the limits of codes. The stress ratio of steel frame columns and frame beams are controlled under 0.75. All main targets are satisfied codes. The paper also expatiated on the mechanics performance of two-way steel truss and space curve-frame columns.
Keywords: steel frame-core system; ring structure; two-way steel truss; transfer stories; space curve-frame columns
