I'm trying to model an unanchored storage tank using FE software Abaqus.I wanna run a modal analysis and find out the frequencies for main impulsive and convective modes.However,I need some analytical equations for these two in order to verify my results.Magic R Seismic Design of Water TanksThe inferred R (in the 1978 code) varies whether or not the tank is anchored or unanchored.This is a direct result of the 2.5 (unanchored) and 2.0 (anchored) multipliers that the 1978 code authors used,which was geared to penalize unanchored tanks (i.e.,require a higher base shear force for design).Once we convert the 1978 base shearJak niezakotwione zbiorniki magazynowe cieczy zachowuj In addition,these findings suggest that tank maximum base shear and moment computed using current seismic provisions for tanks may not be on the conservative side for unanchored tanks.The tank base uplift time-history analyses results computed with the mechanical and SDOF methods were similar in terms of number of cycles and magnitude of the

unanchored tanks Free body Analysis#0183;The fragility curves of two critical failure modes,i.e.,the buckling of the shell plate and the plastic rotation of the shell-to-bottom plate joint,are then developed based on a simplified model of the tank,where the uplift behavior is correctly modeled from the static pushover analysis.Analysis of unanchored liquid storage tanks under seismic Because of cost,cylindrical,ground supported liquid storage tanks are often not fixed to their foundation,even in seismic areas.For such an unanchored tank made of steel,the weight of the cylindrical shell is mostly insufficient ' to prevent local uplift due to seismic overturning moments.Although,for properly designed connecting pipes,uplift itself is not a problem,it results in Analysis of unanchored liquid storage tanks under lateral Many liquid storage tanks consist of a steel cylindrical shell,which is welded to a base plate,but not fixed to the foundation.When such an unanchored tank is subjected to lateral loads due to earthquake induced hydrodynamic pressures in the liquid,the tank wall

unanchored tank,in addition to these mechanisms,uplift of tank base,sliding of the tank and successive contact and separation between base plate and foundation can be observed when tank subjects to seismic loadings.The analysis tool used to quantify the tank behaviour has to take into account the effects of all aforementioned factors.(PDF) Uplifting Response of Unanchored Liquid-Storage TanksA study of the principal effects of base uplifting on the seismic response of laterally excited,unanchored,cylindrical liquid-storage tanks is made.The analysis is implemented by a procedure(PDF) Seismic Response of Unanchored Liquid Storage TanksUnanchored liquid storage tanks under strong seismic loading may exhibit uplifting of their bottom plate,with significant effects on the dynamic behavior and the structural integrity of the tank.
