OPTIMIZATION OF ABOVE-GROUND CYLINDRICAL REINFORCED CONCRETE TANKS UNDER BLAST LOADING CONSIDERING FLUID-STRUCTURE INTERACTION EFFECTS USING THE PSO ALGORITHM
Above-ground storage tanks are significantly more vulnerable to damage from blast loading compared to bury or semi-buried concrete and steel tanks, primarily due to their exposed nature. To accurately assess the real behavior of above-ground tanks, it is essential to account for fluid-structure…
