深圳中航城超高层结构分析与设计

Structural Analysis and Design of Super High-rise Building of Shenzhen Catic City

深圳中航城项目D1地块包括1栋189.6m高的办公塔楼和41.6m高的商业裙房。塔楼采用框架核心筒结构,裙房采用框架结构。塔楼底部加强区核心筒剪力墙外墙角部及外围框架柱采用了钢管混凝土组合构件。论文介绍了塔楼地基基础及上部超高层结构体系特点;采用基于性能目标的抗震设计方法,以反应谱分析为基础,结合弹性时程分析、中震分析和大震Pushover分析结果对关键构件进行了性能化设计,结果表明,结构可以满足规范要求并达到预期的抗震性能目标。

D1 plot of Shenzhen Catic City project includes a 189.6meters high office tower and a 41.6meters high commercial podium.Frame-core wall structure was applied in the office tower and frame structure was applied in the commercial podium. Composite concrete-filled steel tube members were used in external corner tube walls and external frame columns of the bottom strengthened zone.This paper introduces the characteristics of foundation and super high-risestructure, based onresponse spectrum analysis, combined with elasticity history analysis, design earthquake analysis and pushover analysis,the key structuralmembers were designedwhich performance-based anti-seismic design method was used, the results show the structure meet the standard requirements and achieve the desired anti-seismic performance goals.
