This chapter outlines the use of reinforced concrete in bridges. Reinforced concrete is a versatile material, used in most modern bridges in some way. It can be shaped for architectural effect; it can be precast to standardise, and it is used in structures from small culverts to major bridges and viaducts.

Construction Control of Reinforced Concrete Arch Bridges
Journal of Bridge Engineering, 2003Reinforced concrete arch bridges are ideal to span over river valleys or deep ravines. However, the construction of the arch rib is very often the most crucial aspect that may influence the feasibility of the bridge. Casting concrete in situ on formwork and falsework supported directly on the valley is often out of the question.

Structural Evaluation and Strengthening of a Reinforced Concrete Bridge
Journal of Bridge Engineering, 2004This paper deals with the structural evaluation and strengthening of a reinforced concrete bridge over the Arno River in Italy. In 1996 truckload tests and finite-element calculations were performed to assess the bridge condition. The structure was found to be inadequate to bear both the first- and the second-class road loads prescribed by the Italian ...

Concrete integral abutment bridges with reinforced concrete piles
Structural Concrete, 2014AbstractThe use of reinforced concrete (RC) piles in integral abutment bridges (IABs) has not been widespread due to concerns over pile flexibility and the potential for concrete cracking. This is the reason why the use of steel piles is the preferred solution in the United States.

GFRP Reinforced Concrete Bridge Decks
2000This report investigates the application of glass fiber reinforced polymer (GFRP) rebars in concrete bridge decks as a potential replacement or supplement to conventional steel rebars. Tests were conducted to determine the material properties of the GFRP reinforcement, and experiments were performed to study aspects of GFRP rebar placement in actual ...

Assessment of Reinforced Concrete Highway Bridges
Transportation Research Record: Journal of the Transportation Research Board, 2016The primary contributor to the corrosion of bridges in Canada is heavy use of de-icing salts, which can lead to severe rebar corrosion and girder soffit spalling in reinforced concrete (RC) highway bridges. This paper discusses recent challenges faced by authorities in dealing with corrosion problems in Canadian highway bridges, and describes typical ...

Aesthetics of reinforced concrete arch bridges [PDF]
, 2015 Development of RC arches is presented in the paper and aesthetical parameters of more than hundred concrete arch bridges, built worldwide in past 140 years, are analysed. Aesthetics of representative bridges was questioned by surveys and discussed in the paper.

REINFORCEMENT CORROSION AND THE DURABILITY OF CONCRETE BRIDGES.
Proceedings of the Institution of Civil Engineers, 1984Corrosion can arise in most parts of a bridge substructure or superstructure and usually results from the use of de-icing salts. Substructure corrosion is often associated with leaking joints, faulty drainage or salt spray from traffic. General corrosion is found on substructures and although this is a relatively slow process, producing only small ...

Corrosion Evaluation of Reinforced Concrete Bridges
Structures Congress 2005, 2005Current inspection procedures used to assess bridge conditions subjected to corrosion of reinforcing steel involve the use of sounding technique (e.g. chain drag for bridge decks), half-cell potential test, chloride analysis and depth of cover measurement.
