| Research Abstract |
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.
