2021-1-6  Prestressed girders are particularly economical when longer beam lengths are required; some types are suitable for spans of up to 200 feet. Prestressing the concrete reduces the size of the required cross-section and the depth of the beam. The smaller cross-section size reduces the self-weight of the beam by requiring less concrete.

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. The bridge is upgraded for HLPV resulting in an increase in the unfactored live loads applied to the beam.

More than 200 studies have been reviewed and summarized here with a focus on the repair of reinforced concrete (RC) bridge girders which contribute to more than 60% of the bridge inventory in the US [21].

2020-5-22  Precast plank bridges can be obnoxious since there is no haunch, and thus no room for tolerance. However, the issues here are rarely due to differences in expected camber and rather differences due to inconsistencies with the precaster. These are typically addressed via allowable camber tolerances in the specifications.

If this curvature is extended to the outer edges of the bottom fiber, strains at the extreme fibers would be: ε=± 2.088×10−6 rad in. ×13 in =± 27×10−6 in. in.

2021-8-4  According to the United States 2014 National Bridge Inventory the number of concrete bridges far outstrips the number of steel bridges. Reinforced Concrete: 253,336. Prestressed Concrete: 148,333. TOTAL CONCRETE: 401,669. versus. TOTAL STEEL: 181,095. Why would concrete

A Good, Hard Look at Prestressed Concrete. Steel corbels embedded in precast concrete girders support drop-in girders. This 300-foot span over the Gulf Intracoastal Waterway at Sargent Beach, Texas, uses a combination of pre-tensioning and post-tensioning. It is the longest span in the United States using precast girders hauled over land.

2020-9-2  What prestressed concrete designs do is induce stresses throughout the entire structure. The end result is a product that better handles vibrations and shocks than conventional concrete. In addition, this makes it possible to form longer, thinner structures that can still handle those heavier loads.
