【摘要】 采用退化迟滞模型,代表叠层橡胶隔震支座的非线形滞回恢复力特性,对基底隔震结构的动力反应进行了研究。通过算例,对叠层橡胶支座水平剪切刚度对基底隔震结构隔震效果的影响进行了定性的分析。结果表明:在峰值位移反应处于允许范围内时,适当的降低隔震系统的刚度值,可以达到较为理想的隔震效果。更多还原

【Abstract】 By using degenerated and hysteresis model to represent the nonlinear hysteretic restoring-force character of the laminated rubber isolation bearings,dynamic reaction of base-isolation building was studied.In this paper,the author analyzed how the change of stiffness of horizontal shear influenced isolating affection of base isolation buildings.Analysis results indicate that in the allowable range of the maximum displacement reacting,base isolation has obviously seismic isolation effect through properly decreasing stiffness of horizontal shear of base isolation buildings.更多还原
