In the two form deck worksheets, the form deck is assumed to be "inverted" and not to contribute to the flexural moment capacity of the slab. The shear capacity of the composite deck alone is added to the beam shear capacity of the concrete to arrive at the total beam shear capacity of the slab.ģ. In the "Composite Deck" worksheet, since the composite deck is interlocked or engaged with the concrete, the deck is assumed to function as the positive moment, bottom face slab reinforcing.

This program is based on the following references: There is information on the metal deck properties, as well as reinforcing bar and welded wire fabric data tables.ġ. Also, for concentrated loads, the effective slab strip widths for both moment and beam shear are determined. Specifically, the flexural moment capacity for both positive and negative strong axis moments, one-way beam shear, punching shear, and deflection are all evaluated and checked. Both composite deck slabs and form deck slabs can be analyzed and designed for 3 different loading conditions. "DECKSLAB" is a spreadsheet program written in MS-Excel for the purpose of analysis and design of slabs on metal deck.
