Application of nonlinear fluid–structure interaction methods to seismic analysis of anchored and unanchored tanks

Tuning mass of internal flexible wall to reduce seismic demand on exterior walls of liquid storage tanks

“…They found that flexibility has only appreciable impact on impulsive pressure, while convective pressure is not affected by wall flexibility. Ozdemir et al [12] using their experimental results verified finite element simulations accounting for different form of nonlinearity in structure.…”

Liquid-containment shells of revolution: A review of recent studies on strength, stability and dynamics

“…Taniguchi et al [37] presented a procedure for evaluating the liquid pressure on the rigid flat bottom of a cylindrical tank, caused by the uplift motion of the un-anchored base. More recently, Ozdemir et al [38] employed a fully nonlinear fluid-structure interaction FEM modelling for the seismic analysis of both anchored and un-anchored tanks. They validated their modelling through comparisons with available experimental results, and went on to evaluate the provision for seismic design as contained in various seismic standards (API 650, Eurocode 8 and others).…”

Seismic assessment of unanchored steel storage tanks by endurance time method

“…Malhotra (1997) also studied soil-supported unanchored tanks and found that the hydrodynamic base pressures reduce the uplifting resistance as well as the energy dissipation capacity of the base plate. Study of the behavior of unanchored liquid storage tanks and the effect of their fl oor fl exibility is still under way (Larkin, 2008;Ozdemir et al, 2010).…”
