ABSTRACT:
A non-composite impact-resistant structure of lightweight construction is particularly useful in offshore power stations where weight is a prime consideration, and also is useful as the roof of inland power stations. The structure is fabricated from two types of sheet metal units and reinforcing elements which are enclosed thereby. An inner cellular panel is secured to outboard members of a building framework. The cells of the inner cellular panel extend vertically or horizontally when used as a wall structure or may reside in a generally horizontal plane when used as a roof structure. Outer corrugated panels (or outer cellular panels) are secured outboard to the inner cellular panel with the corrugations (or cells) of the outer panel perpendicular to the cells of the inner panel. The inner cellular panel cooperates with the outer corrugated panels to define passageways providing peripheral metal enclosure for reinforcing elements. The reinforcing elements positioned within the passageways increase the shear resistance of the structure, increase membrane development in the inner cellular panels, and produce local damage to impacting tornado-borne debris. A decorative sheathing may be applied outboard of the outer corrugated panel, if desired.
