Deformation and Stress in a Horizontal Reservoir Supported along Generators

Abstract

In this paper, the deformations and stresses in a horizontal reservior supported along two generators and partially filled with a liquid are discussed, utilizing the fundamental differential equation of a thin cylindrical shell introduced by one of the authors. In order to give an accurate distribution of the stresses near the supports, the analysis is performed without assumptions of the distribution of the support reactions along generators. By investigating the relationship between the position of the supports along generators and the maximum stress caused in the reservoir, the optimum position of the supports is studied. Numerical results show that both deformations and stresses in the horizontal reservoir supported along two generators are smaller than whose no supports when the tank is long.
