Prestressed Concrete Bridges

Philadelphia’s Walnut Lane Bridge, completed in late 1950, is considered the first major prestressed-concrete bridge in the U.S. Gustave Magnel, a Belgian engineer, and Charles Zollman, Magnel’s student, designed the bridge. Each of the post-tensioned concrete beams was cast at the bridge

The prestressed concrete bridge girder shown in Fig. 6.9 spans 21.6 m and supports a superimposed dead load G of 6 kN/m and a live load Q of 20 kN/m (excluding self-weight). A 150-mm thick topping slab was cast over the top flange of the beams after full stressing.

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.

05-09-2013  In the field of bridge engineering, the introduction of prestressed concrete has aided the construction of long-span concrete bridges. These often comprise precast units, lifted into position and then tensioned against the units already in place, the process being continued until the span is complete.

IN PRESTRESSED CONCRETE BRIDGE CONSTRUCTION

ching method as applied today for prestressed concrete bridges was first used in 1965 at the Inn Bridge Kufstein, Austria. After the Second World War, bridges were designed on the principle of the minimum consumption of materials. Later on, the labour component of the construction costs became increasingly large, as a consequence of

17-05-2021  The effective prestressing force is transferred from the pretensioned strand to the concrete. In those same regions, slip occurs between strand and concrete due to the difference in strain condition. Research has indicated that the strand end slip can be used as a quality control measure for the bond of prestressing strands.

A simple two-lane bridge made of prestressed concrete was taken and analyzed under the specifications of IRC 6, IRC 18 and IS 1343 recommendations. Various span-depth ratios were considered at which stress criteria and deflection criteria get satisfied. Box girder showed better resistance to the torsion of superstructure.
