摘要
提出了在连廊与主体结构之间设置柔性连接方式,采用SAP2000 Nonlinear结构分析程序,对连廊采用柔性连接和刚性固结进行对比分析。分析结果表明连廊采用柔性连接后,连体结构自振周期增大,楼层加速度减小,结构在连廊连接处的受力状况得到改善,柔性连接具有一定的耗能能力,提高了连体结构的抗震性能,在设计中宜优先考虑柔性连接方式。
This paper presents a flexible connection between the corridor and the main structure, and analyses and compares the corridor of flexible and rigid consolidation by using the ETABS three-dimensional structural analysis program, The results show that the natural period is increased by adopting flexible connection. The floor acceleration decreases. The structure of connections in the corridor force status improved. Flexible connection has certain ability of energy dissipation, so the structure seismic performanc is improved. Therefore, priority should be given to flexible connection in the design.
