摘要
介绍了利用主次子结构的截断模态综合法进行主次组合结构动力分析方法，通过对 传递函数的分析，揭示了巨型框架悬挂体系抗震原理。悬挂体系对巨型框架的驱动作用是该 结构体系的主要特征，巨型框架悬挂体系的振动控制取决于对驱动力的控制，提出了用异步 驱动原理来控制悬挂体系对巨型框架驱动力的控制，并提出了巨型框架悬挂体系基于异步驱 动原理初步设计方法。
A dynamic analysis of the megaframe with suspension systems (MFSS) is conducted. The component modal synthesis of the primary-secondary combined system is employed in the analysis.A study of the transfer function of the MFSS offers a physical insight of the earthquake resistant philosophy of the structural system. It is found that the megaframe is characterized by the driving effect of the suspension systems. The vibration control of MFSS depends on the control of the driving force. In addition, asynchronous driving principle is proposed to control the driving forces of the suspension systems to the megaframe. Iinitial design philosophy of the MFSS based on the asynchronous driving principle is presented.
