简要介绍了深圳瀚森大厦工程的结构设计与抗震分析。该工程由改造项目与新建项目构成,结构属于超B级高度及侧向刚度不规则、平面扭转不规则的超限结构,结构设计时采用了多种软件对结构进行了深入分析,并采用弹塑性有限元软件,模拟混凝土从出现开裂直至完全压碎退出工作的全过程中刚度退化和强度恢复,进行了罕遇地震作用下的动力弹塑性时程分析。
Briefly introduces the structure design and seismic analysis of Shenzhen Hexion Building Project. The project consists of the reconstruction project and the new project, the structure belongs to the ultra-B-level and irregular lateral stiffness, irregular plane twist over the structure, the structure design using a variety of software to carry out in-depth analysis of the structure and the use of shells Plastic finite element software was used to simulate the dynamic elastic-plastic time-history analysis of concrete subjected to rare earthquakes from the stiffness degeneration and the strength recovery during the entire process of cracking from cracking to complete crushing and exit.
