Deck Sheet

The document contains deck sheet design calculations. It provides properties of the deck sheet including thickness, grade, area, and moments of inertia. It also lists applied loads including dead load, construction load, and total load. Bending moments and allowable bending capacities are calculated at mid-span and support locations for 3 spans. Deflections are also calculated and checked against allowable limits. The calculations are repeated for a modified deck sheet with different properties and loadings.
