摘要
结合深圳某实际工程案例,对带多层连廊复杂结构体系的分析及设计进行探讨。主要技术问题包括:两栋塔楼(编号为A、B座)在14层、21层、24层设置三道钢结构空中连廊;两栋塔楼主轴方向的振动周期明显不同,且21~24层之间均存在局部不规则,A座镂空,B座竖向收进;连廊支座位于楼层中间位置,与主体结构连接薄弱,连廊体系与主体结构的连接为分析及设计的关键。结合抗震概念设计,通过抗震措施及节点构造保证结构及构件的可靠性、安全性及可实施性。
Combined with a practical project case in Shenzhen,the analysis and design of complicated structure system with multi-story corridor was discussed.The key technical issues include:two towers(labelled Block A and B)are connected by three steel space corridors on the 14 th,21 st and 24 th stories;the vibration periods in the direction of the main axis of the two towers are obviously different,and there are local irregularity between 21 st and 24 th stories,also Block A is hollow,Block B has setback;the corridor support is located in the middle of the story,and its connection with the main structure is weak,so emphasis is focused on the analysis and design for the connection between the corridor system and the main structures.Combining with seismic conceptual design,the reliability,safety and practicability of structures and components are guaranteed by seismic measures and joint construction.
