Construction and Behavior of Precast Bridge Deck Panel Systems
A bridge with precast bridge deck panels was built at the Virginia Tech Structures Laboratory to examine constructability issues, creep and shrinkage behavior, and strength and fatigue performance of transverse joints, different types of shear connectors, and different shear pocket spacings. The …

Optimum design of precast bridge systems prestressed with carbon fiber reinforced polymers
… rapidly growing and has exciting applications in bridge construction. These materials are light, have an excellent resistance to corrosion, and high strength. Because of these advantageous properties, structures reinforced with composite materials are lighter and have longer service life than …

Glulam Timber Bridges for Local Roads
<p>The most common type of bridges on South Dakota (SD) local roads are prestressed precast double-tee bridges. Currently, there is only one double-tee girder manufacturer in South Dakota (SD). In an attempt to provide more bridge type selection options for local governments, a study was performed …

Effectiveness of Alternative Reinforcing Strategies for Non-Contact Hooked Bar Lap Splices
Closure joints are used in precast bridge construction to join two pieces of precast concrete. The pieces of concrete are joined by a lap splice which consists of longitudinal steel sticking out of each precast element and overlapped over the minimum required development length. State departments …

Recommendations for Longitudinal Post-Tensioning in Full-Depth Precast Concrete Bridge Deck Panels
Full-depth precast concrete panels offer an efficient alternative to traditional cast-in-place concrete for replacement or new construction of bridge decks. Research has shown that longitudinal post-tensioning helps keep the precast bridge deck in compression and avoid problems such as leaking, …

Self-Compacting Concrete for Prestressed Bridge Girders
… cost, its use is on the rise worldwide for precast concrete construction mainly due to its ease of placement over conventional concrete. Some benefits of using SCC for precast concrete applications are easily quantified such as faster construction, reduced noise level, and improved surface …
