On the Fatigue of Headed Shear Studs in Steel-Concrete Composite Bridge Girders
<p>Shear connectors are commonly used in steel bridges to join the concrete deck and steel superstructure, providing a mechanism for shear transfer across the steel-concrete interface. The most common shear connector is the headed shear stud. In the current AASHTO LRFD Bridge Specifications on …

Fatigue Performance and Shear Demand Distributions of Clustered Shear Connectors in Composite Bridge Girders
… Highway and Transportation Officials (AASHTO) Bridge Specifications assumes uniform shear flow demands at the steel-concrete interface of composite bridge girders. As stud pitch increases to beyond 24 in or as studs become clustered to account for pre-cast concrete decks, this assumed shear …

Investigations into Flange Surface Friction Effects on Shear Stud Load Transfer in Composite Bridge Girders
<p>Composite bridge behavior is commonly achieved through headed shear studs welded tothe steel girder flange and embedded in the concrete deck. Current AASHTO provisions for estimating demands on shear studs during service-level loading consider only bearing load transfer, neglecting adhesion …
