Analysis of headless shear stud connections
… in the bridge deck to girder system is the steel shear stud connection, which is used to create composite action between the deck and the girder. Numerous researchers have studied this connection from a strength perspective, and the strength equations for the shear connection have been codified. …

Investigations into Flange Surface Friction Effects on Shear Stud Load Transfer in Composite Bridge Girders
… 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 bonding and …

The Viability of Steel-Concrete Composite Girder Bridges with Continuous Profiled Steel Deck
… composite steel girder bridges. However, because shear studs can only be welded to the girder through the steel deck at rib locations, the number of shear stud locations is limited to the number of ribs in the shear span while the spacing of the shear studs is restricted to the rib spacing of the …

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 …

Structural Performance of Longitudinally Post-Tensioned Precast Deck Panel Bridges
… concerning the required post-tensioning force, shear stud pocket placement, and proper joint design. In a recent dissertation (Swenty 2009) numerous recommendations were made for joint design, shear stud pocket design, and post-tensioning force for full-depth precast deck panel bridges. Design …

Finite element modelling of shear connection for steel-concrete composite girders
… element models to trace the behaviour of headed stud shear connectors in composite girders with solid slabs and precast hollow core slabs. The finite element package ABAQUS was used to conduct the analysis. Push-off tests with both types of slabs were simulated taking into consideration all …

Static push-out tests and finite element studies on larger diameter shear studs for composite steel bridges
… link between the deck and the girders are shear studs welded to the girder top flange. The most commonly used shear studs have a 7/8-inch diameter and are welded to the top flange of the beam in a fabrication shop or in the field. A very large number of shear studs is typically needed to …

Behavior and Strength of Welded Stud Shear Connectors
The behavior and strength of welded shear studs are subjects of ongoing study. In recent years, research has shown that the American Institute of Steel Construction (AISC) specification equations for shear stud strength are unconservative for studs placed in deck with ribs transverse to the steel …

Evaluation of Existing and New Test Configuration for Headed Shear Studs
… slab. To ensure proper composite action, shear connectors, typically in the form of headed shear studs, are utilized. Traditionally, the strength assessment of these headed shear studs is made using empirical design specifications that are based on push-out tests, which have been widely …

Construction and Behavior of Precast Bridge Deck Panel Systems
… of transverse joints, different types of shear connectors, and different shear pocket spacings. The bridge consisted of two AASHTO type II girders, 40 ft long and simply supported, and five precast bridge deck panels. Two of the transverse joints were epoxied male-female joints and the …

Evaluation of redundancy in trapezoidal box-girder bridges using finite element analysis
… that would be induced in the system. Further study using the modeling techniques presented in this thesis should begin by verifying or improving upon the assumptions that were made. Specifically, the concrete material model and the shear stud modeling method should be examined in more detail …
