摘要
大底盘多塔楼结构是一种复杂结构体系 ,其抗震设计方法与传统结构体系有较大的不同。综述了大底盘多塔楼结构的分类、动力分析模型、动力特性以及抗震设计方法 ,进一步分析了多塔结构振型参与系数的物理力学概念 ,探讨了常用结构分析软件对其的适用性 ,指出了有待进一步研究的课题。
The multi tower structure with enlarged base is a kind of complicated structure system of which the aseismic design method is different from the traditional system considerably.The classification,the dynamic analysis models,the dynamic properties and the aseismic design methods of this structure system are summarized.The mechanism concept of the participating coefficient of vibration mode for this structure is further analyzed and the suitability of the common structural analysis softwares for it is discussed.Finally,the subjects for further study are pointed out.
