  9. Deck (bridge) - Wikipedia

    en.wikipedia.org/wiki/Deck_(bridge)

    A grid deck uses beams and diaphragms as the supporting structure. The supporting system of a grid deck is analyzed using a grillage analysis. A slab deck is one where the deck is analyzed as a plate. If the slab has a stiffness that is different in two directions (at right angles), then the deck is known and analyzed as an orthotropic deck.
