超高层商住楼结构设计与施工过程关键技术分析

Analysis of Key technology for structural design and construction of super-high-rise commercial and residential building

随着超高层建设项目的日益增多,超限结构设计问题已经引起工程设计人员的高度关注。本文以迪拜一座超高层钢筋混凝土成束筒结构体系为研究对象,利用ETABS、SAP2000、ANSYS和Midas软件对结构的概念设计、荷载计算、施工模拟、徐变变形以及连续倒塌等关键技术进行研究分析,修正原有结构方案设计存在的一些重大安全隐患,从而确保工程结构安全,恢复正常施工。

Due to the daily increase of projects concerning super-high-rise buildings,the problems of out-of-codes structures have been drawn high attention by engineering designers.This paper focuses on the study of a super-high-rise RC core wall structure system in Dubai.The concept of structural design,loading calculation,construction process imitation,concrete creep effects and progressive collapse analysis,are all carried out by making use of ETABS,SAP2000,ANSYS,Midas software.Some significant operational safty hazards of original designed one are then revised,so as to ensure the safety of the project and reconstruction of the building.
