Clarification: Pretensioned prestressed concrete bridge decks generally comprise pretensioned units used in conjunction with cast in situ concrete, resulting in composite bridge decks which are ideally suited for small and medium spans in the range of 20 to 30m and in general pretensioned girders are provided with straight tendons and to use of

SPLICED GIRDERS Spliced concrete I-girder bridges are cost-effective for a span range of 35 to 90 m (120 to 300 ft). Other shapes besides I-girders include U, T, and rectangular girders, although the dominant shape in applications to date has been the I-girder, primarily because of its relatively low cost.

concrete slab on precast/prestressed (PC) HPC Girders Bridge; and a typical cast in place concrete slab on PC UHPC girders. The total width of the bridge including the barrier walls is 12.45 m and its span length is variable. The slab thickness for both bridges is 175 mm, which

Ease of construction, favorable span-to -depth ratios, aesthetic appeal and high torsional stiffness make adjacent precas t prestressed concrete box -beams a popular option for short -to-. However, p ersisting durability and performance issues resulting from longitudinal deck cracking at shear key locations threaten its favorability.

community to extend the span ranges of precast prestressed girders beyond the 160-ft limit that bridge designers and contractors had been comfortable with for almost 40 years. This demand stems from the desire to reduce costs due to minimizing the number of bridge piers

In-depth analyses is performed to check criteria for lifting and hauling based on methods described in PCI document CB-02-16-E, "Recommended Practice for Lateral Stability of Precast, Prestressed Concrete Bridge Girders". Two methods are provided for the analysis of hauling (shipping) the girder to the bridge site.

The stadium, originally constructed in 1925 is now home to two professional sports teams, the Portland Timbers and the Portland Thorns. The latest expansion to the stadium added 4,000 seats to the east grandstand using precast/prestressed concrete cantilevered raker beams, risers, walls and stairs.

298 / JOURNAL OF BRIDGE ENGINEERING / SEPTEMBER/OCTOBER 2001 LIVE-LOAD DISTRIBUTION FACTORS IN PRESTRESSED CONCRETE GIRDER BRIDGES By Paul J. Barr,1 Marc O. Eberhard,2 and John F. Stanton3 ABSTRACT: This paper presents an evaluation of flexural live-load distribution factors for a series of three- span prestressed concrete girder bridges. The response of one bridge, measured during a static

precast modular beams, planks and decking units, and prestressed concrete bridge components. The flexibility of Humes' bridge solutions allows for the easy adaptation of standard unit sections, providing a choice of geometric envelopes to meet access and waterway requirements from 2 m to 38 m span.

Precast/Prestressed Bridge Girders Athul Abraham Alex, M.S. University of Nebraska, 2016 Advisor: Christopher Y. Tuan A variety of design and construction practices are feasible when building precast concrete continuous bridges with long spans. Precast, prestressed concrete continuous bridges have been implemented by countries around the world.
