大型LNG储罐隔震简化计算方法

Simplified Calculation Method for Seismic Isolation of Large LNG Storage Tank

鉴于目前LNG储罐隔震设计计算方法过于繁琐的问题,本文提出一种整体理论分析结合反应谱弹性数值分析的方法,通过两阶段分析,准确计算带有隔震支座的大型LNG储罐在地震作用下结构产生的效应,为带有隔震支座的LNG储罐在地震作用下的计算提供了一种简便、可靠的工程计算方法。

In view of the current problem that the calculation method of LNG storage tank seismic isolation design is too cumbersome,this paper proposes a method of overall theoretical analysis combined with response spectrum elastic numerical analysis.Through two-stage analysis,the structural response of large-scale LNG storage tanks with seismic isolation bearings under earthquake action is accurately calculated,which provides a simple and reliable engineering calculation method for the calculation of LNG storage tanks with seismic isolation bearings under earthquake action.
