    WisDOT Bridge Manual Chapter 19 – Prestressed Concrete July Introduction This chapter provides information intended for ressed Iprest -girders. Prestressed box girders and general prestressed concrete guidelines are also included in this chapter.   There are three major forms of construction: Solid slab deck (infill deck), Beam and slab deck, Voided bridge deck. Solid slab is ideal for short spans with shallow construction depths. Beam and.

    Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Concrete pipes are used for spans of to 3m and concrete box can be employed for spans of to m. Precast U shaped culverts and arch shapes applied for spans of .

The U.S. Route 7 bridge over the Norwalk River is a single span bridge composed of 15 prestressed adjacent box beams. The bridge carries two lanes of traffic and two shoulder lanes, with a relatively shallow clearance over the river.

The bridge was constructed in and spans meters (m) (48 feet. According to the NBI, box beam bridges account for % of the totalbridges in the United States. Since box beam bridges are typically used for shorter spans and the NBI only considers bridges with spans of 20 feet or more, the number of these bridges is likely even higher.

Precast concrete box beams are still widely used in new. Figure 7 - This is an advertisement for Northern States Prestressed Concrete Co., with an illustration of their block beams as used for the Lake City Bridge spans. Compare this view with the photo of the beams in Figure 6 (see view 2 upper right), showing the side of the block-beam with the post-tensioning strand on the outside of the beam.

• Rolled or welded girders for spans of 50 feet or less • Bolted or welded plate girders for spans over 50 to feet • Bolted or welded trusses for spans over feet The superstructures of grade separations carrying railroad traffic are usually of beam and girder construction. Prestressed Concrete Bridge.

If concrete material is placed under compression before applying the loads, then it is called as prestressed concrete. To construct pre stressed concrete bridge, pre-stressed concrete blocks are arranged as deck slab with the help of girders.

These blocks are suitable for shorter span to longer span bridges. Table 1. Segmental precast, post-tensioned box girder bridges Bridge and Location Year Spans ft. of Boxes Cells Per Box b ft. b ft.

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