摘要
连体结构受力较复杂,连接形式的选择及连接节点的设计尤为重要,其是结构设计的重点和难点.对某双塔高位连体结构进行分析,研究表明,采用可滑动弱连接型式更适合本工程.连接体采用双层钢桁架结构,选用铅芯隔震橡胶支座与塔楼进行连接.计算分析表明,双塔可满足大震不倒,高位弱连接体可达到大震下不掉落的抗震设防目标.
Abstract
The stress of the connected structure is complex,so the selection of connection form and the design of connection joint are partic-ularly important,which are the key and difficult points of structural design.This article concentrate on a twin-tower high-rise connected structure,which indicates that the sliding weak connection is preferable.Double-layer steel trusses is adopted,lead rubber bearing with core is used for the connecting structure.Dynamic elastic-plastic analysis under the rare earthquake action is used,the twin towers can withstand and the high-rise weak connecting structure can not fell off the towers by the analysis.
