隔震层参数设计探讨
|
摘要
对隔震设计中隔震层标准位移与阻尼比的合理设计进行了探讨,给出了铅芯橡胶支座阻尼比的理论计算公式,提出了依据设防烈度设计隔震层的思想.依据我国现有规范与规程,推导了隔震层位移反应的相关公式,探讨了支座标准位移与隔震层阻尼比的合理设计方法.
Reasonable design about displacement and damping ratio of base-isolated story was studied in this paper for seismic isolation design.The theoretical formula for damping ratio of lead rubber bearing was proposed,and the ideology of base-isolated-story design via earthquake fortification intensity was also introduced.Based on the national design code and specification,the corresponding formula for the displacement response was derived.Meanwhile the design method about base displacement and damping ratio of base-isolated story was investigated in this study.
