Abstract
A part of internal strain energy of rubber bridge bearing is transformed into thermal energy, so that temperature rise will be observed on high damping rubber bearing under repeated shearing deformation. It is, however, difficult to measure directly internal temperature subjected to large deformation. But internal temperature affects much on physical characteristics of rubber bearing. As the internal strains of rubber bearing under shear deformation are approximately condidered as uniform, so that energy absorption of rubber is assumed to be uniform. By the hybrid prediction analysis taking both experimental and numerical analysis into account, internal temperature distribution of rubber bridge bearing under repeated shear deformation, is analyzed.
