STUDY ON SEISMIC RESPONSE CHARACTERISTICS OF LAMINATED RUBBER BEARINGS USING REAL-TIME ON-LINE TEST

There is concern about the occurrence of long-period ground motions in Japan. In particular, if seismic isolation building subjected to a motion, device likely affect horizontal performance by resonance and long repeated deformation. As evaluation methods, two analysis methods have been proposed. They are “detailed method” “simplified method”. “Detailed an method that considers repetitive dependence changing at each step time history response analysis. “Simplified calculated steps. First, using model parameters devices. Next, cumulative absorbed energy amount per unit volume calculated, reduction rate calculated. Finally, deformation taken into consideration performing calculation parameter.
