中国华电大厦结构设计

Structure Design of China Huadian Mansion

中国华电大厦由办公楼和酒店两部分组成,结构体系比较复杂。设计中采取框架-剪力墙体系,重要部位为型钢混凝土构件,基本避免或有效控制了可能存在的错层、刚度突变等平面与竖向不规则的不利因素。着重介绍了主体结构方案和角部11.10m跨悬挑构件、连桥等几个关键部位的设计思路、设防原则、计算方法、构造措施。对复杂结构采用了两种软件进行对比分析,并进行了多遇地震下的弹性时程分析。

China Huadian mansion has a very complicated structure system. During the project designing, a series of measures were taken to avoid or effectively control the potential irregularity in horizontal and vertical direction such as diaphragms discontinuities, rigidity varieties. It emphasizes on the design idea, principle of fortification, calculation method as well as the detailed measures for the overall structural plan and several key parts like 11. 10m overhanging member in the comers, connecting bridge. Two types of software were used to analyse the complicated structure system, and elastic time-history analysis was also done.
