Performance of Stud Clusters in Precast Bridge Decks

Performance of Stud Clusters in Precast Bridge Decks. A new design approach to clustered stud shear connection in composite bridges with precast decks is required to accommodate highly concentrated shear force in small area.

Experimental Investigation of a Slip in High-Performance

8/29/2019 · The headed stud shear connectors are usually used to resist longitudinal slip and vertical separation between the steel beam and concrete slab. In general practice, construction of steel-concrete composite girder bridge, I-shaped steel beams, or a small steel box girder flange of the steel beam structure are used [8,9]. Compared with I-shaped ...

Design Considerations

SlenderWall delivers the precast industry’s only 100% thermal-break plus air-barrier panel connection system. This proprietary connection, ThermaGuard, is a series of stainless-steel fasteners anchored to the steel stud frame that create an air gap between the precast concrete panel and the frame, reducing thermal transfer by as much as 25%.

STR-923-2 element to the speed and durability of the modular bridge system (Burak & Seraderian, 2010). Specifically, the study aims to quantify the fatigue performance of stud shear connectors in precast decks compared to CIP decks.

Composite construction

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 ...


typically take advantage of monolithic construction to ensure adequate performance (i.e. near full composite action) and hence they cannot be easily disassembled and reused at the end of the service life of the structure. Furthermore, the demolition of monolithic concrete-steel composite floors in which the shear studs have been

Full-Depth, Precast Concrete Bridge Deck Panel

Shear connectors clustered in groups can be used and should be made to match the shear pocket locations of the precast panels. 2. Experimental investigation (NCHRP 12-65) has shown that the stud cluster spacing can be extended up to 4 ft (1.2 m), without affecting the full composite behavior of the system, if confinement for the stud group and ...

Strength and Fatigue Resistance of Clustered Shear Stud

(1) The static test results suggest current AASHTO shear stud-strength design provisions are unconservative. However, this is balanced by fatigue test results suggesting current AASHTO shear stud-fatigue provisions are probably too conservative, which explains why there have not been widespread in-service performance problems.
