[A-12] 27만 kl급 초대용량 LNG저장탱크 콘크리트 외조의 최적단면 결정을 위한 변수영향검토 = Parametric study of Large LNG storage tank for deciding maximum section of Concrete outer tank

다국어 초록 (Multilingual Abstract)

The purpose of this study is to seek for optimum outer tank section of 270,000kl capacity large LNG storage tank. In this study, diameter of inner tank is chosen for decisive factor. Because inner tank diameter affects dimension of the section mostly.
Increased and decreased rate of stress, amount of major material and approximate construction cost are analyzed for each inner tank diameter 90m, 92m, 94m regarding stability and economic feasibility.
From analyzed results, it was found that the smaller in inner tank diameter, the less in stress in case of applying dead load, LNG pressure and prestress loads at the same time under the same capacity. Also the smaller inner tank diameter decrease amount of major material and total construction cost.
Accordingly, optimum inner tank diameter is conclude with 90m. Since, increased loads by increased diameter and height can counterbalance with pre-stress load, that secures stability and is also economical considering land use efficiency and total construction cost.
