摘　　要：某项目地上二层设有环形连廊连接四栋体量差异大、结构形式不同的塔楼及裙房,四栋塔楼两两之间尚有高位连体。重点介绍了环形连廊的结构设计方案,通过对设置不同支座连接方案进行比选分析,研究环形连廊对各塔楼及裙房的影响,找到了对其自身变形可控同时对塔楼影响最小的支座连接方案,并对塔楼及裙房采取有针对性的加强措施。研究表明此方案下环形连廊对各塔楼影响较小,依此方案进行分析和设计,能有效降低结构的复杂程度,避免形成多连体复杂结构。A ring corridor is set on the second floor of a project to connect four towers and podium buildings with large volume differences and different structural forms,and there are high conjunctions between the two of the four towers.The structural design scheme of ring corridor was mainly introduced.Through the comparison and analysis of different connection schemes,the influence of the ring corridor on each tower and podium building was studied.The support connection scheme with controllable deformation and minimal influence on the tower was founded,and targeted strengthening measures were taken for tower and podium building.The study shows that ring corridor has little influence on each tower under this scheme,and the analysis and design according to this scheme can effectively reduce the complexity of the structure and avoid the formation of multi-connected complex structure.
