ABSTRACT:
A corrugated sheet for use as part of a composite concrete deck comprising parallel spaced crest surfaces connected to parallel spaced soffit surfaces by upstanding connecting web surfaces that converge towards each other as they approach a common crest surface, all the crest, soffit and web surfaces being generally planar with at least the crest surfaces furthermore being provided with upstanding, continuous, longitudinally extending beads made from the crest surface material and with laterally extending upstanding projections running between the beads and connecting them together. The panels between the beads and the projections function as shear panels. An alternate embodiment provides shear panels that are slightly depressed with respect to the surrounding surface material, projections that have flat upper surfaces, and a panel edge portion that is shaped to enable the panels to be secured together in overlapping relationship. The web and soffit surfaces may also be provided with beads and cross projections.
