高层框架-核心筒结构抗震防线问题研究
|
摘要
框架-核心筒因能发挥框架和筒体两种结构体系的优点,是高层建筑常用的一种结构形式.但在地震作用下,框架和核心筒能否协调工作抵抗地震作用以及能够如何有效的发挥"两道抗震防线"一直是备受关心的问题.集中讨论了该结构体系的两道抗震防线——核心筒和外框架的地震力分配特点,概述了增强第一道抗震防线——核心筒延性及提高第二道抗震防线——外框架刚度、延性的一些常用方法,并对它们应用于地震区框架-核心筒结构时的优缺点进行了分析.
Frame-core wall is a type of structure frequently used in high-rise buildings.In this paper,on focus are the distribution characteristics of the earthquake forces in the core wall and outer frame,i.e.two earthquake fortification lines in this structure system.The commonly used methods are summarized,and adopted to intensify the first fortification line—the ductility of the core wall and to increase the second fortification line—the stiffness and ductility of the outer frame,and their advantages and disadvantages are analyzed respectively.
