| Abstract: | Rubber interlayer was used as the seismic isolation of LNG storage tank,which was taken the finite element analysis before and after seismic isolation to earthquake response respectively,Before and after seismic isolation the earthquake response of LNG storage tank's outer wall are calculated under El Centro Wave,Taft Wave and Tianjin Wave. the modality,shift and acceleration are analyzed comparatinely,then the rubber interlayer seismic isolation's seismic isolation effect to LNG storage tank is obtained. |
