초록
내부탱크의 파손에 따른 외부탱크의 누설 안전성을 검토하기 위해서 PC 구조물의 누설 저지효과에 대해 고찰하고자 한다. 이러한 누설 안전성 해석은 완전 방호식의 PC 구조물로 제작된 외부탱크가 내부탱크로부터 유입된
This paper presents safety analysis of LNG leakage in a prestressed concrete outer tank, which is strongly related on the leak checking effects of the PC structure with and without a residual compression zone based on the BS 7777 codes. The full containment type outer tank which is constructed by a prestressed concrete may be destroyed by leaked cryogenic fluids. The FE calculated results show that the total leak checking time of the PC structure with
