Seismic response and damage evaluation for anchored and unanchored cylindrical above ground steel tanks

This paper aims to first present a review of studies on numerical modeling and seismic response analysis above ground steel liquid storage tanks. On that basis, procedure for estimating dynamic parameters associated with simplified models anchored unanchored conditions together calculation methods responses damage states tanks are presented. In which, the nonlinear behavior bottom plate in case caused by sliding uplift phenomena is properly modeled based static pushover 3D finite element model. Finally, an example water tank The both compared evaluated detail.
