【摘要】 采用夹层橡胶垫作为LNG储罐的隔震装置,对LNG储罐在隔震前后的地震响应进行有限元分析。计算了隔震前后LNG储罐外壁在ElCentro波、Taft波和天津波作用下的地震响应。对模态、位移和加速度进行对比分析,得出了夹层橡胶垫隔震装置对LNG储罐的隔震效果。更多还原

【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.更多还原
