Abstract

Abstract: This paper introduces an optimization method for the design of prestressing system for the outer wall of large-scale reinforced concrete LNG storage tank under the condition of inner tank leakage, including the finite element model of outer tank, the computing method and the analysis of results. The influence of prestressing system on the internal force distribution, reinforcement and liquid tightness of outer tank wall under the condition of inner tank leakage is studied in detail.

Key words: finite element, LNG storage tank, prestressing system, reinforcement of tank wall, liquid tightness, leakage condition
