Abstract:
This paper presents analytical calculation of stresses in spherical tank which was used during designing of tank, and experimental verification of calculated stresses after the tank was produced. Derivation of equilibrium equations for the shell element is presented as well as procedure for determination of membrane state of stress. Experimental verification of tank is described. Experiments showed concentration of stress at the points of spherical tank support. Maximum equivalent stress exceeds yield stress for material out of which tank was built, but the area with exceeded stress is very small so it can be neglected. Therefore it is not necessary to reinforce the spherical tank at the points of support.
