摘要
The viscoelastic multi-dimensional earthquake isolation and mitigation device is a new kind of passive control device, which can perform its "name-giving" task of earthquake isolation and earthquake mitigation simultaneously. In order to quantify its vertical earthquake isolation and mitigation effect on structures, firstly, shaking table tests on steel frame structures with and without the devices were carried out; secondly, analysis on dynamic characteristics and dynamic responses of the structures was also performed; furthermore, the finite element analytical results and the experimental results were compared. It can be shown from the analytical and experimental results that the devices have noticeable earthquake isolation and mitigation effect in the vertical direction.
