It is known that the high damping rubber used for building damping material may show a hardening phenomenon when the shear strain attains beyond 2. For reliable simulations considering this hardening effect, an additional hysteretic rule of high-damping rubber is proposed based on the result of cyclic loading tests. The hardening effect in the hysteretic rule is derived by adding a new element considering the difference of stress in the large strain range between the existing hysteretic rule of high damping rubber and the cyclic loading test results.
