The Analysis of Inground LNG Storage Tank Compression Ring Behavior during Concrete Pouring

콘크리트 타설에 따른 지하식 LNG 저장탱크 컴프레션 링 거동 분석

Compression ring is a part of LNG storage tank. The main function of the compression ring is connected the roof plate with concrete side wall. End of its one side is embedded in the side concrete wall and the other's connected with the roof plate by welding. It is designed to support stably for all the loads such as self weight of steel roof, inner pressure and concrete weight. We fulfill the FEM analysis to analysis the compression ring behavior during construction. Also we studied the effect of the change of design variables. On the basis of the results, we could introduce a more reasonable design method for compression ring.
