Dynamic analysis and seismic performance evaluation of above-ground liquid-containing tanks

Effect of Earthquake Characteristics on Seismic Performance of RC Elevated Water Tanks Considering Fluid Level within the Vessels

“…A number of authors have investigated effects on steel and reinforced concrete elevated water tanks by considering a single earthquake record [4,6,9,23,24], and [24]. However, only a few of the researchers considered multiple records, such as Livaoglu [8], who considered two earthquake records for a ground rectangular tank and Panchal and Jangid [26], who considered six earthquake records in their investigation on the seismic behavior of steel elevated water tanks.…”

“…The effect of fluid interaction on the seismic response of water tanks has been the subject of many studies in the past years [4][5][6][7][8][9][10][11]. Also, the effect of soil interaction on the seismic response of elevated water tanks has been studied by many authors [7][8][9]12], and [13].…”

Resonant frequencies in an elevated spherical container partially filled with water: FEM and measurement

“…Moreover, Livao glu and Do gang¨un (2007) investigated the embedment effects on the seismic response of fluid-elevated tank-foundation-soil systems in which the fluid-structure interaction was taken into account using a Lagrangian fluid FE approximation. The seismic performance of elevated cylindrical tanks damaged during the 1999 Kocaeli earthquake in Turkey analyzed by dynamical analysis using a simplified three-mass model were reported by Sezen et al (2008).…”

Response of Ground Supported Cylindrical Tanks to Harmonic Loading

“…Typical damages to tanks during past earthquakes include: buckling of tank walls due to excessive development of compressive stresses, rupture of tank shell at the location of joints with pipes, collapse of supporting tower of elevated tanks , cracks in the ground supported reinforced concrete tanks, etc. (3,4) The primary interest of this study is to evaluate the natural frequency both impulsive and sloshing modes of vibrations and dynamic response to harmonic loading of cylindrical ground supported concrete tanks. Parametric study is carried out on circular tanks with different aspect ratio, using finite element software ANSYS.…”
