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 disposed about a neutral axis. Each such major wave is provided with a plurality of spaced-apart, discontinuous, web zones, each web zone comprising a plurality of interlinked longitudinally extending wave-like stiffeners superposed thereon. The wave-like stiffeners follow the general major corrugated pattern of the major wave thereof. A plurality of spaced-apart flange zones are formed on the panel, the flange zones comprising spaced-apart flattened areas deformed from the general corrugated pattern of the general major corrugated pattern of the panel. The panel is also provided with spaced-apart flange stiffeners. Furthermore, such flange stiffeners which are distributed along the major wave, always project from the exterior of the curvature of the major wave and are always directed towards the neutral axis of the panel. 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. |
