内罐影响下LNG储罐外罐地震响应分析
|
摘要
为了考虑内罐在不同方向地震动时对LNG(液化天然气)储罐外罐的影响,对有内罐和无内罐情况下LNG储罐外罐进行了地震响应分析。结果表明:有内罐时地震响应比无内罐时小,内罐的存在对LNG储罐抗震有好的影响;竖向地震波对结构振动的影响不能忽视。
In order to consider the influence of inner tank of LNG storage tank on seismic response of its outer wall,seismic response analysis of the wall of LNG storage tank with and without inner tank was carried out.Results show that the seismic response of the LNG storage tank with inner tank is smaller than that of LNG storage tank without inner one,existence of inner tank is favourable to earthquake resistance of storage tank and the influence of vertical seismic wave on vibration of the storage tank could not be neglected.
