Seismic response of base-isolated liquid storage tanks considering fluid–structure–soil interaction in time domain

The effect of earthquake frequency content on the seismic behavior of concrete rectangular liquid tanks using the finite element method incorporating soil–structure interaction

“…Also, Cho et al [43] obtained the same results as Livaoglu [21] showed that structural response values are reduced as soil stiffness decreases. The liquid sloshing height and motion were not affected.…”

Soil–structure interaction effects on base-isolated buildings founded on soil stratum

“…(42) The assumption of equal response for the initial and the equivalent undamped systems leads to equality of the stiffness ratios R s andR s [32]. Neglecting the non-diagonal terms according to a procedure proposed by Veletsos and Ventura [51], the generalized damping ratios matrix can be cast in the following form:…”

“…Shenton and Hampton [40] have compared the response of fixed-base and isolated water tanks to demonstrate the effectiveness of base isolation in reducing the deformations, base shear and overturning moment, especially for tanks with low water capacity. Two studies by Kim et al [41] and Cho et al [42] provide information concerning the seismic response of isolated liquid storage tanks. According to these studies, the deformation and force-undertaking demands are reduced in tanks founded on soil of low stiffness.…”

Demand-Based Optimal Design of Storage Tank with Inerter System

“…The vulnerability of tanks during earthquakes has been demonstrated in previous studies [2][3][4][5][6]. Based on the observations of several other researchers [7][8][9][10], the failure modes of tank damage can be divided into several types, such as buckling of tank walls, failure of link facilities, spillover of stored liquid, and uplifting of anchorage systems. Strengthening, isolation, and hybrid methods have been promoted by several researchers to ensure that storage tanks are not damaged during earthquakes [11][12][13][14][15][16][17][18].…”
