description The invention relates to a method for calculating stress of a ring rib cylindrical shell structure. The method comprises the steps of S1, determining the size of the ring rib cylindrical shell structure, wherein the size of a shell plate comprises the radius R of the inner surface of a shell and the thickness t of the shell plate; the size parameters of the ribs are determined according to the structural form; the method further comprises the steps of rib spacing l, calculation pressure Pc, elasticity modulus E of the material and Poisson's ratio mu of the material; s2, calculating related parameters according to the size of the annular rib cylindrical shell structure, wherein the related parameters comprise rib parameters including a rib area A, a rib root radius Rw, a rib panel radius Rf, a rib core radius Rc and a rib effective area Aeff; shell parameters are u and beta; s3, calculating the stress of the shell plate, wherein the stress comprises the longitudinal total stress sigma 1 of the inner surface of
