A seismic design model of base-isolation rubber bearings for nonlinear dynamic analyses is investigated especially under low temperature conditions. The rubber bearing tests are carried out in low temperatures environment up to -30 C deg. to identify temperature dependency of mechanical behavior. A rheology model including elastic-visco-plastic elements is developed to reproduce strain-rate dependent response prominent in high damping rubber bearings and elastic-plastic response in lead rubber bearings.

研究了适用于非线性动力分析的基础隔震橡胶支座的抗震设计模型，特别是在低温条件下。橡胶支座试验是在-30℃以下的低温环境中进行的。以确定机械行为的温度依赖性。建立了一个包含弹-粘塑性单元的流变模型，以再现高阻尼橡胶支座的应变率相关响应和铅芯橡胶支座的弹塑性响应。
