Bridge Design Prestressed Concrete Bridge Deck Design

28/01/2020  There are three concepts involved in the design of prestressed concrete : Prestressing transforms concrete into an elastic material. By applying this concept concrete may be regarded as an elastic material, and may be treated as such for design at normal working loads.

Prestressed concrete bridges: design and construction

Prestressed concrete decks are commonly used for bridges with spans between 25m and 450m and provide economic, durable and aesthetic solutions in most situations where bridges are needed. Concrete remains the most common material for bridge construction around the world, and prestressed concrete is frequently the material of choice.

28/01/2020  The three most common types of reinforced concrete bridge decks are : Solid slab bridge decks are most useful for small, single or multi-span bridges and are easily adaptable for high skew. Voided slab and beam and slab bridges are used for larger, single or multi-span bridges. In circular voided decks the ratio of [depth of void] / [depth of ...

Bridge Design Composite Bridge Deck Design

28/01/2020  With continuous spans the concrete slab will crack in the hogging regions and only the steel reinforcement will be effective in the flexural resistance, unless the concrete is prestressed. Generally the concrete deck is 220mm to 250mm thick with beams or plate girders between 2.5m and 3.5m spacing and depths between span/20 and span/30.
