shear stud clusters to be grouted to the precast concrete panels in the horizontal position simulating construction techniques and using the same grout mix for similar specimens. To isolate the performance of the shear studs, petroleum jelly was spread over the top
(5) Full depth precast deck panel system (Yamane et al. PCI J 1998): This system provides a stemmed precast panel provided with blind shear pockets. The shear connectors and pockets were designed to create full composite action with the supporting girders utilizing a mix of headed and headless studs to facilitate deck removal.

Deform Stud SNP shear stud Standard specification for steel stud assemblies for shear reinforcement of concrete ASTM A1044 has also allowed the use of double-headed studs produced from ribbed steel. SNP STUDS are produced from ribbed reinforcement, which has higher yield strength more than 3,500 ksc. Diameter of stud 12.7 mm. and 15.2 mm. Special
shear stud pockets longitudinally spaced 2 ft on-center. Shear studs were welded on the girder within the pockets of the panels; the pockets were then filled with grout that was also used to fill the haunch between the girder and deck. Figure 2. Precast deck panel configuration Shear Stud Pocket (Typ.) Block-out for Longitudinal
The welded shear stud is the standard connector used today, but other connectors, such as the through-bolt connector, may have advantages for precast construction or applications where better fatigue resistance or deconstructability is desired. The standard method of assessing the performance of a shear connector is through the use of push tests.
Amerect Inc. - Steel Erector/Precast Erector - is available as either a prime contractor or sub-contractor for the performance of quality erection services. The company specializes in the following services: Structural steel erection ; Steel joist and metal floor and roof deck erection, placement of shear studs
Precast concrete shear wall panels are used to provide lateral load resisting system when combined with diaphragm action of the floor construction. The effectiveness of precast shear walls is largely dependent upon the panel-to-panel connections. In some cases, precast panels are used as formwork for cast-in-place concrete.
precast ribbed floor systems Shear Stud Capacity Typically composite shear capacity expressions are based on tests in which concrete splitting is prevented before stud fracture or stud pull-out occurred (Hyland et al 2001
The experimental program included 16 large-scale tests using four configurations of shear stud spacing that ranged from a typical cast-in-place deck detail with studs every 12 in. or 24 in. to configurations more conducive to precast panels with clustered shear studs spaced at 36 in. and 48 in.

To investigate the shear performance of horizontal joints for short precast columns with sleeve grouted connections, and explore the conditions under which shear failure occurs along the joint, two short cast-in-situ concrete columns and two short precast concrete columns were tested under cyclic horizontal loading.
possible that an enhanced understanding of the performance of welded shear studs in composite beams, including system effects, may allow for relaxed design provisions. High strength bolt shear connectors may be a viable alternative to shear studs in some cases, providing greater fatigue resistance due to the absence
shearing studs can significantly influence the shear bearing capacity of group studs and that the number of studs is inversely proportional to the average decrease in the bearing capacity of a single nail. However, they did not examine the slip distribution. By testing the shear performance of shear studs in early strength concrete, Topkaya [19 ...

Abstract. In this paper, a connection between precast beam and precast slabl to be used in decks of precast composite bridges is studied. The difference between this connection and the common connection used in bridge construction is that in this paper the steel connector is associated with a shear-key which is formed on the top face of the precast beam, and a high, performance concrete is ...
Design of shear connectors for precast concrete decks in concrete girder bridges. Afshin Hatami, University of Nebraska - Lincoln. Abstract. Full-depth precast concrete deck systems have several advantages over traditional cast-in-place concrete decks. Higher concrete quality, accelerated construction, and reduced life-cycle cost are the main ...
