Abstract

Abstract

The roof of large storage tank is prone to instability under external pressure due to its thin wall and large span. Taking a large 20 000-ton composite storage tank as an example, in order to improve the stability of the tank roof, four reinforcement schemes were proposed, such as composite arch reinforcement, composite arch-I-beam-channel steel combined reinforcement, I-beam-channel steel combined reinforcement, and triangular steel truss reinforcement. A finite element model was established to perform buckling analysis of the tank roof before and after reinforcement. It was shown that the stability coefficient of the tank roof before reinforcement was 1.29, which was much smaller than the requirements of a stability coefficient of 15 in Steel pressure vessels (GB 150—1998). Except for the composite arch reinforcement, other reinforcement schemes that combined steel structures with composite materials exhibited favorable effects, and the stability coefficient of the tank roof after reinforcement could meet the requirements of GB 150—1998. Based on this, the cost and construction processes of each reinforcement scheme were systematically analyzed. The small cross-sectional triangular steel truss reinforcement scheme was identified as the optimal solution for the composite tank roof, which could provid technical reference for the reinforcement and optimization design of large composite storage tank roofs.
