【摘要】 在隔震结构Benchmark模型的基础上,建立了相应的动力反应计算方法及计算程序,并在理想化隔震层刚度布置的情况下研究了隔震层水平刚度分布对基础隔震结构地震响应的影响。通过针对Benchmark模型设计的3种隔震方案的计算结果比较表明:当隔震层刚度中心靠近结构质心时,能显著降低结构的扭转反应,但同时增大了水平位移分量。文中在隔震结构Benchmark模型上建立的计算方法和结论为隔震体系计算和隔震方案设计提供了可靠的依据和途径。更多还原

【Abstract】 The dynamic calculation methods and calculation procedures were adopted on the basis of the base-isolated benchmark building,and the effect of the horizontal stiffness distribution of the isolation layer on the seismic responses of the base-isolated structure was studied for an idealized stiffness distribution of the isolation layer.The results of the three isolation schemes,which were designed according to the benchmark model,show that the torsional response would be reduced while the lateral response would be increased when the stiffness center of isolation layer is close to the mass center.The dynamic calculation methods developed on the basis of the base-isolated benchmark building provide a reliable basis for the isolation system calculation and isolation design.更多还原
