Abstract

A novel isolation seismic bearing model named the double-N SMA-rubber bearing was proposed and designed in this paper. The basic design idea was to add SMA wire bundles closed around the rubber bearing to improve the whole mechanical properties of the isolation seismic bearing. The corresponding theories equations and the working mechanism of this new isolation device were deduced. The application of this isolation model which was employed in the model shaking table test of a 1000m³ storage tank was presented. Different test working conditions and seismic excitations were given to analyze the structure response of the storage tank and the presented bearing properties. The presented bearing model was used in the first working condition. The displacement and acceleration responses of vertical tank model were obtained. Only the rubber bearing without SMA bundles was applied in another working condition. Meanwhile the structure response results were gained and contrasted with the former results. The experimental results show the presented isolation seismic model is effective in absorbing energy and can be used in the isolation seismic design of the vertical storage tanks.
