摘要
将隔震橡胶和调谐液体阻尼器(TLD)减震机理相结合分析了水浮力系统的隔震机理.通过试验探究了有限界域内水在不同深度时的自振频率,测定、计算了结构在不同柔性支座布置形式、不同水深条件以及不同介质下的动力放大系数、阻尼系数和体系自振频率,得出了在水深增大过程中结构隔震效果明显增强的结论.
The seismic isolation mechanism of buoyancy system is analyzed by combining isolation mechanism of the rubber bearing and the tuned liquid damper.The natural frequency of water with varied depths in bounded domain is studied through experiments.And the dynamic magnification factor,damping coefficients and natural frequency of building with different allocations of rubber support,water depths and mediums are determined and calculated.It is concluded that the structure has better seismic effect while the water depth increases.
