摘要
提出一种组合结构减震体系，即在两相邻结构之间用连接件相连，形成一个主、子结构的组合体系．通过时程分析法探讨了主、子结构耦合振动机理，以及连接件位置、刚度对两结构响应的影响．分析结果表明：合理设置连接件能有效地控制组合结构（主要对主结构）的响应．并且，运用最优控制理论对分析结果进行了讨论．
An analysis of vibration reduction in a composite building is given. The composite building consists of two parts, of which one is a main building and the other a substructural one, and is connected each other by a spring element. These buildings connected are two neighboring buildings. The coupling mechanism of the building vibrations, the effects of the connected positions and the stiffness of the spring elements on the building vibration are discussed. The Wilson θ method is used for step by step numerical integration of the equation of motion. The numerical results show that the vibration of the composite building, including the main and substructure parts can be controlled effectively, specially for the main building, if the relative parameters of the connective elements are selected suitably. The calculating results are compared with the ones given from the optimal control theory.
