ABSTRACT OF THE DISCLOSURE A corrugated metal building panel (e.g.,made of steel) is provided herein. The panel has at least one (and preferably two) longitudinally extending major waves. Each such major wave is provided with a plurality of spaced-apart, discontinuous, longitudinally extending wave-like stiffeners superposed thereon. The wave-like stiffeners follow the general major corrugated pattern of the panel. The spaces between the stiffeners include flattened portions of the general major corrugated pattern of the panel but in a preferred variant, also includes some wavelike corrugated portions interspersed between the flattened portions. Furthermore, the stiffeners which are distributed along the major wave, always project from the exterior of the curvature of the major wave. In this way, the local buckling factor is improved and the section modulus is increased, with the degree of improvement in local buckling factor and section modulus being optimized by the selection of a particular configuration from a series of alternative configurations. Thus, the strength and rigidity of the corrugated panel is increased.
