“…With this second approach, not only the natural period of the structure is considered; the damping characteristics, inertia and restoring terms are also relevant in the dynamic analysis. Real motions of the structure are the outcome of this process and such motions can be compared with design limit states, for instance (Banerji et al 2000, Frandsen 2005, Delorme et al 2006, Attari andRofooei 2008).…”

“…Modelling TLDs fluid responses has been conducted using a range of approaches mostly based on mechanical analogies (Tait and Deng 2008), potential flow models of the free surface fluid flow (Frandsen 2005, Attari and Rofooei 2008, Ikeda and Nakagawa 1997, Ikeda 2003 or most commonly, non-linear shallow water wave theory (Sun and Fujino 1994, Reed et al 1998, Banerji et al 2000, Tait et al 2005. None of these has tried to properly model the effects of breaking waves on increasing the dampening effects of the TLD devices.…”

The roll motion response of a single degree of freedom (SDOF) structural system to which a rigid rectangular partially filled liquid tank has been attached is considered. The SDOF structural system with the empty tank is first described with a mathematical model and this model is validated by performing decay experiments as well as experiments in which periodic excitations are applied to the system. The responses are accurately predicted by the model. The accuracy of these predictions allows us to study both experimentally and numericaily, with weakly compressible SPH, the performance of the partially filled tank as a tuned liquid damper (TLD). The sloshing flows inside the tank comprise the onset of breaking waves which make the TLDs devices extremely difficult to model, especially for the potential flow multimodal approaches commonly used to simúlate these sorts of coupled systems. In order to characterise the wave breaking effects on the response curves, tests have been performed with liquids of different viscosity, the increasing viscosity preventing the onset of breaking waves. The capabilities of SPH to treat this coupling problem are assessed and the results show that SPH is able to capture a substantial part of the physics involved in the addressed phenomena but further work remains still to be done relating to a more accurate treatment of the laminar viscosity and turbulence effects. RESUME La réponse en roulis d'un systéme a un degré de liberté (SDOF), auquel est fixée une cuve rectangulaire partiellement remplie de liquide, est étudiée dans cet article. Dans une premiére partie, un modele mathématique est proposé pour le systéme SDOF, calibré a l'aide de résultats expérimentaux d'oscillations libres et forcees, avec une excitation périodique. La réponse du systéme est reproduite avec precisión par le modele. L'efficacité de la cuve en tant qu' amortisseur liquide (TLD) est ensuite analysée expérimentalement et numériquement en utilisant la méthode de simulation SPH. Pour résoudre ees problémes de couplage, des méthodes basées sur la théorie du potentiel sont généralement utilisées. Dans le cas présent, leur utilisation est limitée a cause de la formation de vagues déferlantes lors du ballotement du liquide dans la cuve. Une plus grande viscosité du liquide réduisant la formation de ees vagues, des expériences ont été effectuées avec des liquides de différentes viscosités pour quantifier l'impact des déferlantes sur la réponse globale du systéme couplé. La capacité de la méthode SPH pour résoudre ce probléme est discutée et les résultats montrent que les principaux phénoménes physiques sont reproduits avec SPH. Cependant, des travaux restent nécessaires quant au traitement de la viscosité laminaire et a la partie turbulente de l'écoulement.

“…Edwards, 1969 was the first researcher to consider tank's flexibility in establishing hydrodynamic forces on ground-supported cylindrical tanks subjected to horizontal earthquake ground motions, and to employ the finite element technique to dynamic analysis of liquid storage tanks. Many investigations (Shaban and Nash, 1975;Kana and Dodge, 1975;Haroun, 1980;Attari and Rofooei, 2008;Kalani sarokolayi and Navayineya, 2008;Moslemi, Kianoush and Pogorzelski, 2011) have been conducted for analyzing water storage tanks under translational components of the ground motion. Actually earthquakes movements cause translational components generated during a seismic event are always being accompanied by rotational components due to traveling wave effects.…”

The dynamic behavior of a liquid storage tank as a special structure differs from that of general structures. Important structures of cylindrical shape are used to store vital products, such as water and petroleum products, for cities and industrial facilities. Damage to these structures during a strong ground motion may lead to fire or other hazardous events. Liquid storage tanks are lifeline structures and strategically very important, since they have vital use in industries and nuclear power plants. In this research, an example reinforced concrete (RC) elevated water tank, with 900 cubic meters capacity, is studied under three pairs of earthquake records and analyzed in time history by using mechanical and finite element modeling techniques. The liquid mass of the tank is modeled as lumped masses known as sloshing mass, impulsive mass and rigid mass. The corresponding stiffness constants associated with these lumped masses are worked out depending upon the properties of the tank wall and liquid mass. Tank responses including base shear, overturning moment, tank displacement, and sloshing displacement under these three pairs of earthquake records are calculated, and then the results are compared and contrasted. Results show that the system responses are highly influenced by the structural parameters and the earthquake characteristics, such as frequency content.
