| 摘 要： | 通过三幢平面布置基本对称的多层建筑结构地震实测结果,分析偶然扭转的影响。讨论了扭转位移比超过限值的允许条件,并列举了几个典型的工程实例进行验证。对上部无刚性连接的大底盘多塔楼结构的周期比验算提出近似计算方法,并通过工程实例说明此方法在设计中的应用。

| Abstract: | Accidental torsion influences on building structures are analyzed resorting to the recorded motions of three multi-storey buildings with nominally symmetrical plan during earthquake.The conditions of exceeding the limits for torsional displacement ratio are discussed,and some typical structural examples are presented.An approximate method is advanced to check the period ratio of the multi-tower building structures with large podium and without rigid connections between towers,illustrating its applications in structural design with some examples of building structure. |
