“…The damaged forms of wall of storage tank mainly are: the bottom of tank wall is as the "elephant foot", tank wall is instability like a "diamond" and the whole wall of storage tank is curved seriously [6][7][8][9][10]. The reasons of the phenomenon are the form of the axial instability and strength destroy is caused by hoop tensile stress and axial tensile stress concurrently .The excessive deformation of tank wall does not necessarily cause oil leakage, but stress will tear the connection of the wall and the bottom of tank.…”

“…Most previous studies focused on the dynamic performance of the inner tank, but the effect of water sloshing in the inner tank on the outer tank has been rarely considered. [35][36][37] Aiming to address the above issues, we presented in this paper a benchmark shaking table test to investigate the overall seismic responses of extra-large prestressed RC LNG storage tanks under strong seismic excitations. The model structure was scaled from a real LNG storage tank of capacity 160,000 m 3 by a scaling factor of 1:14.…”

In recent years, many large‐scale liquefied natural gas (LNG) storage tanks have been built all over the world. Due to their high constructional cost and important functions to the public, the academic and engineering communities are very concerned with the operational safety of these important infrastructures once subjected to potentially disastrous actions, that is, earthquakes, typhoons, tsunamis, and so forth. This work presented a benchmark test in evaluating the aseismic performance of extra‐large prestressed reinforced concrete (RC) LNG storage tanks. A 1:14 scaled model of the prototype LNG tank was designed and constructed for shaking table tests. Two recorded and two artificial earthquake ground motions with peak ground acceleration (PGA) up to 1.2g were selected successively as seismic inputs to the tank. The acceleration, displacement, shear force, and strain responses of the model structure were presented, analyzed, and discussed in detail. It was found that due to the differences in the frequency spectra, the seismic excitations have distinct influences on the responses of the tank model. In particular, the wall‐roof junction was detected as the weakest part of the outer tank, and the filling water had non‐negligible effects on the overall seismic responses of the tank. Verified finite element simulations were also presented as supplements to the experimental study. Some suggestions were made with the aim to improve the designs of LNG storage tanks.

Shi et al (2012) studied the dynamic buckling performance of fluid-solid coupling about a large liquid-storage tank. Tao (2013) solved the unsteady fluid-structure interaction (FSI) problems with large structural displacement by partitioned solution approaches.…”

The purpose of this paper is to study the seismic response of a base-isolated, concrete rectangular liquidstorage structure (CRLSS) under small-amplitude sloshing. In this study, the three-dimensional FEM of the base isolated CRLSS is established by using ADINA. The concrete material is assumed to be nonlinear and elastic, and the criterion for the small amplitude sloshing is defined to determine the seismic response of a base-isolated CRLSS under different conditions. The results show that when small-amplitude sloshing occurs and the nonlinear elasticity of the concrete material is considered, the displacement of wallboard, the height of liquid sloshing and the equivalent stress are increased with the increase in the earthquake intensity when comparing the same liquid height and different intensities of a bidirectional earthquake. The liquid height is found to affect the seismic response of the base-isolated CRLSS. The lower the liquid height is, the larger the equivalent stress is, and the greater the displacement of the wallboard and the amplitude of the liquid sloshing are.
