Study on Roof and Wall Thickness Values of Outer Concrete Tank of Full-Containment LNG Storage Tank
英文摘要：The concrete outer tank of a full-containment LNG storage tank consists of circular bottom slab, cylindrical wall and dome roof, and is a statically indeterminate structure. When the finite element analysis is used for the outer concrete tank, the geometric dimensions of the tank should be determined at first and the rationality of these values will affect the efficiency of the analysis. By analyzing the property of the outer tank under the major loads which will control the section design, and taking the requirements of strength and service and load factors under different design limited states into account, the formulas of calculating the roof thickness, haunch thickness and wall thickness are deduced in this paper. The research results have been applied to the designs of Jiangsu and Dalian LNG projects and proved to be correct.
