Abstract A comprehensive study is conducted on finite element modeling and stress analysis techniques of above ground atmospheric bulk liquid storage tanks with foundation settlements. Both 2-D and 3-D modeling are examined for their applicability and limitations. Simple elastic analysis and 3-step method using a hybrid elastic-plastic procedure are explored and compared. In addition, data processing techniques are proposed to extract effective settlements from tank inspection measurements, which could be used for proper reconstruction of a settled foundation in finite element model. Procedures and practices are proposed and demonstrated to improve the finite element modeling and analysis of storage tanks.

This article, basing on the field test stress of an oil-storage tank in the site, investigated finite element modeling method for large oil storage tanks. To study the effects of contact conditions among the tank wall, bottom plate and the foundation, the soil of the foundation, and holing on the tank stress, six different finite element models were built by ANSYS finite element analysis software. The stresses in the tank were calculated under the gravity load and the water pressure. Results of the six models have been compared with the field test values. It was obtained for the stress distribution in the tank wall, bottom plate, and big horn weld and around the manhole from which the influence scope and extent to the tank was investigated. It shows that the calculated stresses have a good agreement with measurement. The plane model has enough precision for the tank stress analysis. The contact conditions and soil affect on the stress in the scope with 0.2H and 0.24H (the height of the tank), and holing affects the adjacent area with 2D (the diameter of the manhole).
