土-结构相互作用对消能减震结构动力特性的影响
Effects of soil-structure interaction on dynamic characteristics of energy dissipating structures
摘要
Abstract
The effects of soil-structure interaction (SSI) on dynamic characteristics of energy dissipating structures were investigated. Motion equations of soil-structure interaction energy dissipating structure were established with the soil dynamic characteristics described by systematic lumped-parameter model. Two parameters , such as soil shear wave velocity and the ratio of building height to foundation width, were used to investigate the effects on the dynamic characteristics energy dissipating structures under different periods and damping ratios by complex mode theory. It could concluded that, when SSI is considered ,the first mode damping of structures without energy dissipation devices, increases when soil shear wave velocity decrease, while the contrary is the case for the structures with energy dissipation devices. Therefore, SSI had more effects on building with energy dissipation devices than building without devices.关键词
