Shear performance of replaced bolt shear connectors in prefabricated composite beam
IABSE Reports, 2022<p>Bolt shear connectors have the advantage of efficient installation and demolition when used in prefabricated composite beams. When bolt shear connectors are damaged in the service period and replaced by new ones, the sheer performance of the replaced bolts will be affected by the existing structural damage.

Fatigue performance of bolted shear connectors
Australian Journal of Structural Engineering, 2021A computer-aided engineering (CAE) fatigue life prediction technique is developed in this paper to determine the fatigue strength of bolted shear connectors in composite structures.

Cyclic Performances of Shear Connectors
Composite Construction in Steel and Concrete VI, 2011Natural cyclic loads such as strong winds and earthquakes can cause changes in bending moment signs in composite structural elements. Consequently, the connectors will be subjected to alternate shear forces. For this reason, the cyclic behavior of shear connectors is particularly important in these loading conditions.

Effect of Orientation on the Shear Strength of Perfobond Shear Connectors
IABSE Reports, 2009<p>In this paper, three perfobond rib orientations, that is, normal orientation, invert orientation and lateral orientation in concrete were selected to invest the effect of perfobond rib orientation in concrete on shear strength by conducting a serial of push-out tests.

Cyclic Behavior of Headed Stud Shear Connectors
Composite Construction in Steel and Concrete IV, 2002Three series of pull-push specimens with 16 mm and 22 mm diameter headed stud shear connectors were built and tested as part of a general investigation on seismic design of steel-concrete composite beams with full and partial shear connection. To assess the shear connector performances from a seismic and damage standpoint, pullpush specimens have been ...

FE analysis of continuous shear connector
IABSE Congress Reports, 2021<p>Composite bridges with encased steel beams, or nowadays, rather encased steel continuous shear connectors are a welcome option for short span railway or road bridges. With lower construction height and easy construction of prefabricated composite beams it brings a new, complex, solution for replacement of older, overserved bridges, as well as ...

Tubular shear connectors for composite construction. [PDF]
Results of an investigation into the behaviour and capacities of tubular shear connectors for -precast and cast-in-situ composite construction in structural steel and concrete are presented. In precast composite construction the connectors are cast in the slabs at the precasting yard and on positioning the slabs over steel beams are welded to their ...

Low-Cycle Fatigue Test on Stud Shear Connectors
Journal of Structural Engineering, 1997In steel-concrete composite beams particular attention has to be paid to the fatigue phenomena in the connection. If each part of the structure behaves elastically the problem can be faced with the classical load-life fatigue approach, but for long-span beams, the slip at interface may reach values that involve inelastic deformation of the connector ...

Continuous Shear Connectors in Bridge Construction
Composite Construction in Steel and Concrete VI, 2011Continuous shear connectors offer an upcoming solution for composite beams. They are characterized by a high initial stiffness, bearing capacity and ductility. With their use new and economic construction methods have been invented, e.g. the PreCoBeams (Prefabricated Composite Beam).
