摘　　要：开展了强风作用下连体高层建筑风致动力响应的研究。以东南沿海地区某实际高层连体建筑为实际工程背景,建立了塔-廊体系有限元模型。采用子空间迭代法分析了塔-廊体系自振频率及振型特点,采用CFD方法进行了该连体结构的风荷载模拟,并在此基础上进行了塔-廊体系风致响应分析。结果表明:塔楼峰值响应随楼层高度增加而逐渐增大。由于塔楼结构存在一定程度的扭转响应,水平方向上各层不同位置的节点峰值响应存在一定差异。A real connected high-rise building in southeast coastal areas was taken as an example to construct the finite element model of the tower-corridor system.The natural frequencies and mode shapes of the system were investigated based on subspace iteration method.The wind loading of the connected high-rise building were numerically simulated using computational fluid dynamics(CFD) and the wind-induced dynamic responses were also examined.The made observations demonstrate that the peak responses of towers gradually increase with increasing structural height.The nodal peak responses of different floors are different to some extent due to the structural rotational responses under wind loading.
