Coupled structural and heat conduction FE analysis of laminated high damping rubber bearing

A framework for coupled structural and heat conduction finite element analysis is developed laminated high damping rubber bearings (HDRBs), analyses are conducted full-scale tests of an HDRB using the shaking table at E-Defense. An HDRB, which used in base-isolated buildings, modeled hexahedral solid elements. The as overlaid viscohyperelastic elastic-plastic constitutive model. However, material parameters identified results subjected to one-directional loading, temperature dependences taken into account by a simple method based on empirical formulae because no cyclic coupon test was tests. combined number loading cases. same mesh both analyses. Analysis presented test, two-directional with elliptical orbit, earthquake test. obtained those compared. coupling effect mechanical thermal behaviors clearly shown results, although reductions equivalent stiffness not large cycles present limited.
