composite behavior precast concrete bridge deck
connections between precast concrete deck panels and bridge girders appears appropriate. Forty-eight-inch spacings were successfully implemented in these recent research and construction projects. Recent research has not, however, examined the behavior of composite decks with shallow beams. As the beam becomes Composite Girder Connections for

composite behavior in precast-decked steel bridges are presented. Two million sinusoidal load cycles at a frequency of 3.5 Hz at levels exceeding those of an equivalent HS 20-44 AASHTO tr1:1ck were applied to a V3-scale laboratory model of a composite, precast-decked, simple-span bridge. Loads, defle.ctions, strain ,
The new precast concrete deck system was fully-composite with the supporting prestressed concrete girder. This was proven by comparing the measured strains and deflections with those obtained from the CIP concrete deck bridge. Therefore, the use of threaded rods as discrete shear connectors and HSS formed shear pockets at 4 ft. spacing was
Experimental and analytical studies of different shear connector types and various pocket spacings were conducted to investigate the composite behavior of precast concrete bridge deck-panel systems.

Using full-depthprecast concrete panels to replace a bridge deck is an innovative approach. The major advantages of the precast concrete system are speed of construction, durability of the bridge deck, and full composite action between the bridge deck and the precast, prestresseci concrete gird ers. Composite action can be achieved between

The 13.8m/45-ft long bridge, which spans Bear Creek, used fiberglass rebar in the footings, abutments, wing walls, parapets and a curved poured-in-place concrete arch. A one-piece, all-composite deck that sits atop the concrete arch was fabricated by Kansas Structural Composites Russell, Kan. .

THiN-Wall. THiN-Wall is a structural load bearing, precast sandwich wall building envelope system that features composite action between concrete wythes. The system enables a very energy efficient building with edge-to-edge EPS or XPS insulation without thermal bridges and uses less concrete than traditional structural wall panels.
This article describes how experimental and analytical studies were conducted to investigate the composite behavior of precast concrete bridge deck-panel systems. A full-scale, single-span bridge was constructed and fatigue and ultimate load tests were conducted with different shear-connector types and various pocket spacing.
Precast Concrete Deck Systems Unlike CIP decks, precast concrete decks are made with concrete slabs that are cast elsewhere and delivered to the site of the bridge for construction. Each segment is about 8 to 12 ft long. Precast decks are usually made of pre-stressed concrete to minimize the risk of damage during transportation. Metal Deck
A deconstructable steel concrete composite bridge deck is proposed. Experimental data on arch behaviour of precast RC deck slabs are provided. Efficiency of cross-bracing and transverse ties for inducing arch action is studied. Application of bolted shear connectors in a deconstructable deck is studied.
For the rapid replacement of the deteriorated concrete deck in steel concrete composite bridges, the precast concrete deck system is very attractive and has been widely used in several countries. Also, the system can be applied to the new construction of composite bridges, which have fewer steel girders and a wide spanning bridge deck.

as a temporary deck to allow placement of a final cast-in-place concrete deck. The advantage of a precast concrete deck is in the acceleration of the construction schedule. Precast panels allow for quicker placement, which, in principle, speeds up overall bridge construction. 10.3 DESIGN APPROACH 10.3.1 Structural Behavior of Concrete Decks
A one-third scale composite steel-concrete bridge model with a precast deck was tested under negative moments to investigate the behavior of the structure before and after cracking of the deck. The model was simply supported and an upward concentrated load was applied at midspan to develop negative moments while the supports were
