The viscoelastic multi-dimensional earthquake isolation and mitigation device is a new kind of passive control device, which has both earthquake isolation and earthquake mitigation abilities. In order to quantify the horizontal earthquake isolation and mitigation effect of this device on structures, shaking table tests on structures with and without the devices and the corresponding analysis on earthquake isolation and mitigation properties are carried out. It can be shown from the experimental and analytical results that the device has both earthquake isolation and earthquake mitigation effects on structures in horizontal direction, and its horizontal earthquake mitigation coefficients can be referred to those of the rubber bearing earthquake isolation structure.
