摘要：

In this study, torsional behaviors of high-damping rubber bearings under various bi-axial seismic waves observed in the site are investigated by time-history analysis with single mass system. A simplified numerical model for the shear properties of the bearings composed of a hysteretic damping element and a viscous damping element is proposed for the analysis. The influences of the characteristic of the seismic wave to the torsional strain generated in the bearings by the effect of damping elements are evaluated. Furthermore, relations between the behavior of the bearings during seismic response and the oval-loading test which is specified for the test of bi-axial ultimate characteristics are examined.
