Axisymmetric uplift mechanism of a cylindrical liquid storage tank
The results of analyzing the static axisymmetric uplift mechanism of liquid storage tanks by the energy method are presented. It is clearly seen that the tank bottom should be considered as a large deflection plate and that no significant differences are found by using the large or small deflection theories for the tank wall. The calculated results show that the maximum bending stresses in the bottom plate will decrease after the uplift displacement reaches a certain level and never meet the yield points. The assumed slide motion of tank bottom on its foundation has noticeable influence on the membrane forces rather than on the bending moments. Moreover, some phenomena observed in the experiments can be qualitatively explained by the analysis. The method presented in this paper is also valid in analyzing the nonsymmetric uplift mechanism of liquid storage tanks.
