摘要: 晟通梅溪湖国际总部中心 A 塔和 B 塔平面尺寸、高度、层数均不相同,两栋塔楼强轴垂直相交。 在方案比选中,对比了连体状态和单塔状态下结构的水平抗侧力性能;分析了连接体高度、连接体层数、连接体楼板和连接体梁系布置等参数对连体结构整体刚度的影响。 采用两种不同计算方法,分析了单塔模型和连体模型的整体稳定性。 结果表明:虽然两栋塔楼刚度存在显著差异,但两栋塔楼结构刚度强轴的垂直布置并采用刚性连接体进行连接的情况下,塔楼之间能通过连接体协同受力强弱互补,使连体后结构具有更好的整体刚度和稳定性。

Abstract: The plane size, height and number of floors of tower A and tower B of SNTO Meixi Lake InternationalHeadquarters center are different, and the main axes of the two towers intersect vertically. In the scheme comparison andselection, the horizontal lateral force resistance of the connected scheme and the single tower scheme were compared, andthe effects of the height, number, the floor slab and the beam system layout of connected floors on the overall stiffness ofthe connected structure were analyzed. Two different calculation methods were used to analyze the overall stability of singletower structure model and connected structure model. The results show that although there are significant differences in thestiffness of the two towers, the strength of the forces between the towers can be complementary through the connectedstructure under the condition that the structural stiffness axis of the two towers is vertically arranged and connected with arigid connector, so that the connected structure has better overall stiffness and stability.
