To study the dynamic behavior of liquid storage tanks,one must distinguish between anchored and unanchored tanks.In the case of an anchored tank,the tank bottom edge is fixed to the foundation.If the tank is unanchored,partial lifting of the tank's bottom may occur,and a strongly nonlinear problem has to be solved.Storage Tanks - The Best Liquid Storage Tanks Cargo Enjoy the ease of customizing your truck or Jeep with Lund Internationals line of the best storage tanks.Lund International offers the industry's broadest range of functional body and appearance products that provide customers with the best ways to customize and personalize their vehicles.

Fatigue analysis of liquid-storage tank shell-to-base

During severe seismic events the base of unanchored steel liquid-storage tanks can uplift,causing large inelastic rotation demands at the shell-to-base connections and large multi-axial stresses (radial tension and circumferential compression) in the tank base-plate.With repeated cycles of uplift,these shell-to-base connections are susceptible to low-cycle fatigue failure.Failure of liquid storage tanks due to earthquake Above ground liquid storage tanks have suffered serious damage during earthquakes.The damage of tanks can vary from local yielding or buckling of the tank wall,to loss of contents,or to collapse which leads to an unrepairable tank.Considerable work has been carried out on this problem with varying degree of success.However,the results are largely directed toward response rather than Failure of liquid storage tanks due to earthquake Above ground liquid storage tanks have suffered serious damage during earthquakes.The damage of tanks can vary from local yielding or buckling of the tank wall,to loss of contents,or to collapse which leads to an unrepairable tank.Considerable work has been carried out on this problem with varying degree of success.However,the results are largely directed toward response rather than
