Jun 27 2017 The first design step for a concrete bridge deck is to choose the correct design criteria. The following concrete deck design criteria are obtained from the typical superstructure cross section shown in Figure 2-1 and from the referenced articles and tables in the AASHTO LRFD Bridge Design Specifications (through 2002 interims).

Bridges - initial design - SteelConstruction.info

Deck slab cantilevers at the edge of the deck will control the position of the outer main girders. A cantilever of 1.5m is common and can work economically with a 250mm deck slab. With these primary dimensional constraints identified the main steel grid can be defined to suit the particular geometry and dimensions of the bridge.

Bridge - Wikipedia

A bridge is a structure built to span a physical obstacle (such as a body of water valley road or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle which is usually something that is otherwise difficult or impossible to cross.
