Design of Bridge Slab Spreadsheet
Reinforced Slab Bridges used For short spans, a solid reinforced concrete slab, generally cast in-situ rather than
precast, is the simplest design to about 25m span, such voided slabs are more economical than prestressed slabs.
Slab bridges are defined as structures where the deck slab also serves as the main load-carrying component, The span
to-width ratios are such that these bridges may be designed for simple l-way bending as opposed to 2-way plate
bending. This design guide provides a basic procedural outline for the design of slab bridges using the LRFD Code and
also includes a worked example.
