摘要:中节能之江华座项目是体型复杂的超大跨转换结构,转换跨度约84~100m,且转换楼层数量多,荷载大。采用钢管混凝土框架-剪力墙结构体系,并利用拱形斜柱进行转换。对该工程的结构体系进行了阐述,针对超限情况提出了抗震性能目标及抗震措施。由于结构体型复杂且超长,楼盖为重要的抗震构件,对楼盖受力进行分析,根据分析结果采取了相应的加强措施。转换斜柱在结构底部形成了很大的水平推力,水平推力的平衡是本结构体系设计的关键,通过在地下室顶板、底板设置钢拉梁,并施加预应力来平衡斜柱水平力。

Abstract: Zhijianghuazuo tower of CECEP is a complex super large-span transfer structure, with a transfer span of about 84~100 m, and a large number of transfer floors and a large load. The concrete-filled steel tube frame-shear wall structure system was adopted, and the arch-shaped inclined column was used for transfer. The structural system of the project was described, and the seismic performance target and seismic measures were proposed for out-of-code condition. As the structure is complex and over-long, the floor cover is an important seismic member, and the floor cover forces were analyzed, and corresponding strengthening measures were taken according to the analysis results. The transfer inclined column forms a large horizontal thrust at the bottom of the structure, and the balance of the horizontal thrust is the key to the design of this structural system. The horizontal force of the inclined column is balanced by setting steel tension beams in the top and bottom plates of the basement and applying prestress.
Keywords: large-span transfer structure; steel pipe concrete; frame-shear wall; arch-shaped inclined column; calculation length coefficient; prestress
