Horizontal Shear Transfer for Full-Depth Precast Concrete Bridge Deck Panels
Full-depth precast deck panels are a promising alternative to the conventional cast-in-place concrete deck. They afford reduced construction time and fewer burdens on the motoring public. In order to provide designers guidance on the design of full-depth precast slab systems with their full …

Precast Full-Depth Deck Panels Supported on Inverted Bulb-Tee Bridge Girders
… (SDDOT) currently uses precast double-tee bridge deck systems for many of its county bridges because they are economical and fast in construction. Current bridges are designed for a service life of 75 years. However, many double-tee girder bridges are deteriorating and some need total replacement …

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, …

Fatigue testing of partial-depth precast concrete bridge deck panels with embedded wire trusses
… for the overhang portions of Texas bridge decks. The panel provides structural resistance alongside standard prestressed concrete panels (PCP) to provide formwork across the entire width of a bridge deck. In total, four total specimens were tested for their performance under differing …

The Investigation of Transverse Joints and Grouts on Full Depth Concrete Bridge Deck Panels
… and blockouts on full depth concrete bridge deck panels. The joints were designed on a deck replacement project for a rural three span continuous steel girder bridge in Virginia. Two cast-in-place and four post-tensioned joints were designed and tested in cyclical loading. Each joint was …

Heat Transfer Assessment of Aluminum Alloy Corrugated Naval Ship Deck Panels under VTOL Aircraft Thermal Loads
The behavior of aluminum alloy ship deck panels under the thermal loads of Vertical Take-off-and Landing (VTOL) capable aircraft has become a question of interest with the introduction of new primarily aluminum alloy ships to the U.S. Naval Fleet. This study seeks to provide an initial …

Structural Performance of Longitudinally Post-Tensioned Precast Deck Panel Bridges
… due to bridge construction is to use precast deck panels. Precast deck panels can significantly reduce the overall length of the construction project. The panels can be manufactured ahead of time, and with higher quality control than is possible in the field. One of the reasons precast deck …

Field and Laboratory Tests of a Proposed Bridge Deck Panel Fabricated from Pultruded Fiber-Reinforced Polymer Components
Two 7" deep FRP deck panels were manufactured and tested in a controlled service environment. The deck panels were 15' by 5' in plan, and were composed of ten 15' long, 6" by 6" by 3/8" standard pultruded FRP tubes. The tubes were sandwiched between two 3/8" thick standard pultruded FRP plates. The …

Investigation of the Structural Behavior of Asphalt/Wood Deck Systems for Girder Bridges
Glue laminated wood deck systems are commonly used for bridge decks on girder bridge systems. These decks are usually covered with a hot-mix asphalt wearing surface in conjunction with a bituminized fabric sheet waterproofing membrane. Often cracks occur in the asphalt at the intersection of two …

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 …

Continuation of Field and Laboratory Tests of a Proposed Bridge Deck Panel Fabricated from Pultruded Fiber-Reinforced Polymer Components
… performance of two 6 3/4 in thick bridge deck panels fabricated by the Stongwell Corporation of Bristol, Virginia. The panels are made of off-the-shelf, pultruded glass fiber-reinforced polymer elements, bonded and mechanically fastened together. The testing involved laboratory stiffness …

Base test method for gravity loaded standing seam roof systems
… be conducted for each combination of purlins, deck panels, and clips that a manufacturer uses. The objective of this thesis is to investigate the possibility of eliminating the size of purlins, the orientation of purlins, length of span, and the presence or absence of insulation from a …

Performance Criteria Recommendations for Mortars Used in Full-Depth Precast Concrete Bridge Deck Panel Systems
The use of full-depth precast concrete bridge deck panels is becoming more and more attractive to transportation authorities throughout the country. In comparison to conventional cast-in-place decks, precast decks are of higher quality, allow for the bridge to be opened to traffic in less time and …

Static push-out tests and finite element studies on larger diameter shear studs for composite steel bridges
… of composite action between the concrete bridge deck and the steel girders. The critical link between the deck and the girders are shear studs welded to the girder top flange. The most commonly used shear studs have a 7/8-inch diameter and are welded to the top flange of the beam in a fabrication …

Strength and Life Prediction of FRP Composite Bridge Deck
… and replacement of deteriorated bridge decks. However, there is lack of proper understanding of the structural behavior of FRP decks. For example, due to the localization of load under a truck tire, the conventionally used uniform patch loading is not suitable for performance evaluation …

Rational load rating of deck-girder bridges with girder end shear cracks in reverse orientation
… distribute the truck live loads from within the deck panels to the surrounding girders and diaphragms. Stiffness matrices are utilized to find the nodal displacements then the reactions at the girder supports caused by the truck live loads and bridge dead load. These reactions are checked against …
