Seismic response of liquid-filled elevated tanks

Experimental and numerical study of dynamic response of elevated water tank of AP1000 PCCWST considering FSI effect

“…The pressure-based fluid element Fluid30 is suitable for fluidstructure interaction analysis (Choi et al, 2013;Hosseinzadeh et al, 2013;Livaoglu and Dogangun, 2006;Moslemi et al, 2011). However, the Fluid30 element ignores the influence of free sloshing phenomenon.…”

“…The fluid element Fluid80 is particularly well suited for calculating hydrostatic pressures and fluid/solid interactions (Hosseinzadeh et al, 2013;Moslemi et al, 2011). Acceleration effects such as sloshing problems may be included.…”

“…It turned out that the distributed added mass with the convective mass is more appropriate than the lumped mass assumptions for finite-element modeling. Moslemi et al (2011) adopted the finite element technique to investigate the seismic response of liquid filled tanks considering the effect of tank wall flexibility and sloshing of the water free surface. El Damatty et al (2005) conducted a small scaled liquid-filled conical tank model to study the elevated water tank.…”

Response of Ground Supported Cylindrical Tanks to Harmonic Loading

“…Sloshing occurs in the upper part of the liquid, which does not displace laterally with the tank wall (6). Hydrodynamic response can be separated into impulsive motion, in which liquid is assumed to be rigidly attached to tank and moves in unison with tank wall and convective motion, characterized by long period oscillations and involves vertical displacement of fluid's free surface (7). The ground supported tanks can be idealized as shown in fig.1.…”

The nonlinear analysis of an innovative slit reinforced concrete water tower in seismic regions

“…There have been numerous studies carried out on water tower regarding its fluid-structure interaction and seismic performance [1][2][3]. However, limited study has been conducted on RC shaft performance [4].…”
