“…Li and Gong 27 , 28 respectively adopted the displacement-displacement format and the displacement–pressure format to realize the earthquake analysis for the hydraulic structure-compressible fluid interaction models. Elansary et al 29 conducted the seismic analysis of liquid storage composite conical tanks by using an in-house developed model that accounts for the hydrodynamic pressure resulting from the vibration of the contained fluid, and the interaction between the fluid and the structure vibrations. These achievements have been successfully applied for the analyese of the seismic behaviors of concrete dams 30 – 32 , and other hydraulic concrete structures 33 , 34 .…”

To ensure the safety operation of inter-basin water transfer project, it is important to understand the seismic performance of shallow-buried large-scale segment-connected pipeline structure under earthquake and other multiple actions. In this paper, a 3D FE model is built in details for the seismic assessment of large-scale prestressed concrete inverted-siphon shallow-buried under riverbed, and a method is proposed to realize multiple interactions of the viscoelastic boundary elements to finite elements, the compressible fluid to structure and the sealed joints made of rubber belt between adjacent segments. The inverted-siphon is longitudinally composited by 58 segments in total length of 858.64 m, and transversally consisits of three rectanguler-section boxes with net dimension of each box of 6.5 m width and 6.6 m height. The main influencing factors are set as the thickness of overburden soil, the flow condition and the engineering geological condition. The time-history analysis is carried out on the 3D FE model under Elcentro seismic wave excitation. The numerical analyses figures out the main vibration modes and vibrational frequency of this inverted-siphon, reveals the regions of peak tensile stress appeared on the concrete surface and the risk sealed joints with extremum relative displacement. This provides a scientific reference to take specific prevention measures of anti-earthquake, based on a deep understanding to the seismic cracking of concrete and the tearing broken of sealed joints for this kind of segment-connected pipeline structure.

“…Subsequently, the dynamic response of liquid contained tanks and the FSI phenomenon have been subjects for extensive experimental and numerical investigations by many researchers. Such studies emerged by the efforts of Jacobsen and Ayre [3], Housner [4], Veletsos [5] and later by other researchers such as Mansour and Nazri [6], Shakib and Alemzadeh [7], Elansary and El Damatty [8], and Moslemi et al [9]. The aim of this study is to provide a comprehensive review for the equivalent mechanical models of liquid storage tanks that account for FSI, including the added-mass, single-lumped-mass, two-lumped-mass, spring-mass, three-mass, and other models that were featured in the literature.…”

Water tanks are considered one of the most important facilities in firefighting systems and municipal water supply. These critical water storage and distribution facilities should remain operable even after a severe seismic event or sustain only damages that can be readily repaired. In recent years, the seismic design of storage tanks has been aimed at fulfilling safety requirements and the environmental impact on society. This paper provides a review of research work related to seismic response of liquid-filled tanks. Major contribution from previous research works related to dynamic behavior of liquid tanks are acknowledged in this review. This paper encompasses the phenomenon of fluid-structure interaction and reviews several equivalent mechanical models for liquid storage tanks that account for this phenomenon. The application of each modeling approach and its accuracy in accounting for the fluid-structure interaction are discussed based on available literature and applicable international standards. It was shown that different equivalent modeling approaches that consider the fluid-structure interaction effects can be used to reduce the computational cost and complexity of liquid-tank systems.
