Fatigue Performance and Shear Demand Distributions of Clustered Shear Connectors in Composite Bridge Girders
… 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 demand distribution may be unrepresentative. Understanding shear transfer and resulting demands …
