Torsional strain is calculated by horizontal bi-directional loading tests, which is known to analyze the images of the dots painted on the surface of high-damping rubber bearings, because it can't be measured directly. In elliptical orbit loading tests, residual torsional strain, which increases the torsional strain, is confimed. A method for evaluating torsional strain based on torsional stress is proposed, which consider an influence of residual torsional strain. Seismic response analyses are performed to evaluate the dynamic behavior of an isolated building under horizontal bi-directional earthquake excitations.
