Shaking table experiment of vibration-controlling suspended-floor structure equipped with viscous dampers
摘要
Abstract
A shaking table experiment of suspended-floor structures equipped with fluid viscous dampers has been conducted in this paper. The effects of link types and the mass ratios between the primary structure and suspended floors and distribution patterns of dampers on responses of suspended-floor structure models were verified. These responses included the frequency, the mode-damping and maximum displacements of suspended-floor structures. Test results show that the frequencies and the mode damping adjusted and the first three modes are mainly influenced by suspended-floor structures with rigid-bar links. Maximum of suspended-floor structures installed with dampers are the shear drift of suspended floors compared with traditional displacements of the primary structure＇s top floor of the suspended-floor structure with dampers are smaller than the traditional suspended-floor structure and slightly smaller than the free suspended-floor structure without links. Moreover, the relative larger mass of the suspended segment is helpful to control the primary structure＇ s dynamic responses. Besides, suspended-floor structures with dampers can effectively control the displacement of suspended floors relative to the primary structure and story drifts of suspended floors compared with free suspended-floor structures. When the lateral stiffness of suspended floors is relatively little, the uniform distribution of dampers is more effective to control the relative displacements of suspended floors than the congregating distribution of dampers.关键词
