Abstract

Abstract

The failure mode and mechanism of floating-roof oil storage tanks under the blast impact through the combustible gas explosion were discussed, on the basis of the scaled model tests and the numerical simulations comprehensively. It is found that the coupled impact effect of the blast wave and the liquid resulted in the bulking failure and damage of the oil storage tank body. In the process of the violent vibration, the stress concentration appeared on the upper area of the scaled model, and the tank body lost its stability and generated the concave formation and dynamic buckling area.
