When quality and performance make all the difference! Building with precast elements has numerous benefits, starting with the higher quality through production in the controlled environment of a precast plant, through to the time saved at the construction site. Connection tech- nology also plays a fundamental role. Whether in trans-
surrounding the shear stud is represented by the portion of the equation to the left of the equality, while the portion to the right represents the resistance of a shear stud. Because the shear stud resistance is written in terms of its tensile strength, it implies that a shear stud behaves in pure tension rather than shear, which seems unlikely.
Extensive research dating back to 1965 has been conducted on the fatigue performance of headed shear stud connectors in steel and cast-in-place composite girders. However, little research has been conducted specifically on the fatigue performance of headed shear stud connectors clustered into pockets.

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
10/11/2016 · A simplified full-depth precast concrete deck panel system for accelerating bridge construction (ABC) is introduced and a finite element analysis (FEA) is conducted to investigate the static and dynamic responses of this conceptual deck system. The FEA results are compared to those of the traditional full-depth precast concrete deck panel system.
Force is transferred between the two materials by friction and, where needed, discrete mechanical connectors, including shear studs that may be attached to an embedded steel section. With all forms of composite construction it is important for the designer not to forget the construction stage. Assuming that there is no temporary propping, the ...

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 ...

girders. Shear studs are typically used for panels installed on steel girders. This research program investigated the performance of shear studs and hooked reinforcing bars with precast, prestressed girders. A portion of the hooked reinforcing bar, which was cast into the girder, protruded from the top flange into the shear pocket. The shear
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.
The shear connection is critical in determining the overall performance of the composite superstructure and is commonly achieved with a grout blockout in a precast concrete deck panel, which accepts a cluster of tightly spaced steel shear studs. No specific equations are found in the CHBDC for the design of shear studs used in this system.
