Shear Stiffness of Two-Inch Wood Decks for Roof Systems.
Abstract
The shear stiffness of a roof deck that is attached to deep roof beams is often counted upon to prevent lateral buckling of the deep beams under design load. Present design methods neglect the deck stiffness in calculating theoretical buckling loads; thus they are unduly conservative and wasteful of material. If the deck stiffness exceeds a certain threshold value, the stability criterion no longer governs the design of the structure. Thus 2-inch decking is of particular interest because of its low shear stiffness. The question is of interest to laminators, structural engineers, architects, and building officials. (Author)
