摘　　要：随着各类建筑工程使用要求的日益增加和钢结构施工技术的逐渐成熟,能兼顾受力需求、使用面积的钢结构体系越来越受青睐,其中采用钢骨混凝土核心筒加钢结构体系的建筑尤为普遍,设计中钢结构支撑、受力体系选择的不同,对于施工方法、施工难度、工期等都有十分重要的影响。钢结构主受力构件选择采用核心筒顶部巨型拱悬吊式结构的设计作法,对设计、施工都有巨大的挑战。以趣店科技金融创新园区项目主体工程1号楼上部主楼为例,对大型悬吊式钢结构施工技术进行分析探讨,可为类似工程施工提供参考。With the increasing requirements of construction projects and gradual maturity of steel structure construction technology,steel structures meeting the requirements for stress and usable area are more and more popular,especially buildings integrating steel-reinforced concrete core tubes and steel structure.The steel structure support and stress system in the design has important impact on the construction method,difficulty and period.The use of the large arch suspension structures at the top of the core tubes of major stressed components of steel structures is greatly challenging for the design and construction.Taking the upper main structure of Building 1 in the major project of Qudian Technological & Financial Innovation Park as an example,the construction technology for large suspended steel structures is analyzed and discussed.
