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

This paper presents theoretical determination of elasticity constants for steam boiler membrane wall as structurally orthotropic plate. Modulus of elasticity and shear modulus are determined in directions parallel and perpendicular to membrane wall pipes for both bending and membrane load. When determining modulus of elasticity for bending load, Engesser's theorem is used for obtaining deflection of membrane wall. After that, from equality of deflections of membrane wall and structurally orthotropic plate, modulus of elasticity is obtained. When determining modulus of elasticity for membrane load, Engesser's theorem is also used, and the expression is obtained from extension equation of membrane wall and structurally orthotropic plate. Shear modulus for both loading conditions are obtained using Poisson's ratios.
