Description Liquid storage tanks are used in industrial plants for storing oil or other petrochemical liquids. In numerous practical applications, aboveground liquid storage tanks are simply placed on the foundation pad. In the case of major earthquakes, these tanks may exhibit uplifting of their bottom plate and the increase of the axial meridional compressive stress acting on the tank´s wall, which may cause structural damage, loss of content and even explosions or other adverse effects. The differential displacements between the tank and the foundation pad can damage the pipe connections, while the increase of the meridional compressive stress can trigger the tank´s wall buckling in the form of elephant´s foot, which is the most typical damage of the tank. Thus, the proposed topic focuses on studying the effects of the uplifting of the tank´s bottom plate on the increase of the stress acting on the tank´s wall, developing a elephant´s foot buckling during this loading. For this purpose a 3D finite element model of the tank is employed, in order to evaluate the tank response under earthquake loading in a quasi-static manner, placing emphasis on the axial meridional compressive stress acting on the tank’s wall.
Required skills - Good knowledge of the Finite Element Method.
