Theoretical determination of elasticity constants for steam boiler membrane wall as the structurally orthotropic plate

Membrane wall of the steam boiler is structurally orthotropic plate. At structural analysis of boiler, finite element of the orthotropic plate is applied, whereat it is needed to have equivalent stiffness of the membrane wall. In this paper, the theoretical procedure of calculating of elasticity constants for membrane and bending stiffness of membrane wall is presented. Theorem of minimum total potential energy is applied. Mathematical expressions are given and by means of them it is possible to calculate equivalent constants of elasticity very simple.
