“…To verify the correctness of the present multimodal system under seismic excitation, the present results of free surface wave height are compared with the experiment results reported by Hosseinzadeh et al [37]. A scaled steel container with 0.002 m wall thickness was used in the experiment.…”

Nonlinear response of liquid partially filled in a rigid cylindrical container with a rigid annular baffle subjected to lateral excitation is studied. A semianalytical approach is presented to determine the natural frequencies and modes of the liquid sloshing. Introducing the generalized time-dependent coordinates, the surface wave height and the velocity potential are expressed in terms of the natural modes of liquid sloshing. Based on the Bateman–Luke variational principle, the infinite-dimensional modal system is given by the variational procedure. The infinite-dimensional modal system is reduced by using the Moiseev asymptotic relations. The resultant hydrodynamic force and moment of the liquid pressure acting on the container mainly depend on the position vector of the mass center of the liquid. Expanding the integral about the weighted position coordinates into the Taylor series about the surface wave height at the unperturbed free surface gives the formula of the position vector of the mass center, which depends only on the generalized time-dependent coordinates. Excellent agreements have been achieved by comparing the present results with those obtained from Gavrilyuk’s solution and SPH solution. Finally, the surface wave height, resultant hydrodynamic force, and hydrodynamic moment for a container subjected to harmonic lateral excitation are discussed in detail.

“…In another study, the unidirectional shaking table test was conducted after fabricating a miniature model of a liquid storage tank and the sloshing behavior of the fluid was measured using a high-definition (HD) camera [18]. The sloshing behavior was measured in another study using an HD camera to experimentally evaluate the effect of the sloshing reduction devices used in steel storage tanks, which are commonly used in petrochemical complexes and oil storage facilities [19]. The 3D sloshing surface of the liquid in a water tank was measured in a small-scale shaking table test in another study by applying the image processing technique to the liquid [20].…”

The occurrence of excessive fluid sloshing during an earthquake can damage structures used to store fluids and can induce secondary disasters, such as environmental destruction and human casualties, due to discharge of the stored fluids. Thus, to prevent such disasters, it is important to accurately predict the sloshing behavior of liquid storage tanks. Tubular level gauges, which visually show the fluid level of a liquid storage tank, are easy to install and economical compared to other water level gauges. They directly show the fluid level and can be applied for various fluids because they can be constructed with various materials according to the fluid characteristics and the intended use. Therefore, in this study, the shaking table test was conducted to verify the validity of the method for measuring the water level response of the tubular level gauge installed on a liquid storage tank using image signals. In addition, image enhancement methods were applied to distinguish between the float installed in the tubular level gauge and the gray level of the background.

“…Much research has been undertaken to investigate the dynamic behaviour of water and petroleum storage tanks that are typically composed of steel material that is different from the steel used to manufacture wine tanks, which in some cases have an open top or a floating roof, and that mostly have a low height to radius (H/R) aspect ratio and are either anchored or are unanchored to their foundation and rest on a concrete ring wall (e.g. see [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]). Currently limited research has been reported on damage data associated with wine storage tanks, with the most comparable earthquake damage data available being collected between 1933 and 1995 and reported by Cooper [26] based on an inventory of 424 water and petroleum storage tanks.…”

The 2013 Seddon earthquake (Mw 6.5), the 2013 Lake Grassmere earthquake (Mw 6.6), and the 2016 Kaikōura earthquake (Mw 7.8) provided an opportunity to assemble the most extensive damage database to wine storage tanks ever compiled worldwide. An overview of this damage database is presented herein based on the in-field post-earthquake damage data collected for 2058 wine storage tanks (1512 legged tanks and 546 flat-based tanks) following the 2013 earthquakes and 1401 wine storage tanks (599 legged tanks and 802 flat-based tanks) following the 2016 earthquake. Critique of the earthquake damage database revealed that in 2013, 39% and 47% of the flat-based wine tanks sustained damage to their base shells and anchors respectively, while due to resilience measures implemented following the 2013 earthquakes, in the 2016 earthquake the damage to tank base shells and tank anchors of flat-based wine tanks was reduced to 32% and 23% respectively and instead damage to tank barrels (54%) and tank cones (43%) was identified as the two most frequently occurring damage modes for this type of tank. Analysis of damage data for legged wine tanks revealed that the frame-legs of legged wine tanks sustained the greatest damage percentage among different parts of legged tanks in both the 2013 earthquakes (40%) and in the 2016 earthquake (44%). Analysis of damage data and socio-economic findings highlight the need for industry-wide standards, which may have socio-economic implications for wineries.
