［摘要］为了研究高层建筑钢框架-偏置筒体结构、钢筋混凝土框架-偏置筒体结构在结构技术性和经济性上的特点，对两种不同结构体系的抗震性能、空间利用率和造价成本进行了分析比较。以深圳某高层建筑为例，对采用两种不同结构体系下结构的变形、抗震性能、空间利用率、工程造价、工期等方面进行综合比较分析。研究结果显示：在抗震性能方面，采用钢框架-偏置筒体结构方案的结构抗震性能更优；在空间利用率方面，采用钢框架-偏置筒体结构方案的结构空间利用率更大；在工程造价方面，采用钢框架-偏置筒体结构比采用钢筋混凝土结构方案的结构造价更高；在工期方面，采用钢框架-偏置筒体结构方案主塔楼标准层总施工工期更短。

Abstract:In order to study the structural technical and economic characteristics of high-rise building steel frame-offset tube structure and reinforced concrete frame-offset tube structure, the seismic performance, space utilization rate and cost of two different structural systems were analyzed and compared. Taking a cultural center in Shenzhen as an example, the deformation, seismic performance, space utilization rate, engineering cost and construction period of the structure under two different structural systems were comprehensively compared and analyzed. The research results show that: in terms of seismic performance, steel frame-offset tube structure has better structural seismic performance. In terms of space utilization, the space utilization rate of steel frame-offset tube structure is greater. In terms of engineering cost, steel frame-offset tube structure is more expensive than the reinforced concrete structure. In terms of construction period, the total construction period of the standard floor of the main tower of steel frame-offset tube structure is shorter.  

Keywords:steel frame-offset tube structure； seismic performance； space utilization； engineering cost； construction period
