Behaviour of demountable shear connectors in composite structures
… is to evaluate the feasibility of demountable shear connectors as an alternative to welded shear connectors in composite structures through push off tests and composite beam tests. Push off tests were conducted to examine the shear strength, stiffness and ductility of demountable shear …

Horizontal Shear Connectors for Precast Prestressed Bridge Decks
… as for new bridge construction. The horizontal shear strength at the interface between the two interconnected elements is of primary importance in order to provide composite action. The strength of the bond between the two precast members should be high enough to prevent any progressive slip …

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 …

Standoff screws functioning as mechanical shear connectors in composite joists
… standoff screw functioning as a mechanical shear connector are presented. In all tests, the base material, through which the screw was fastened, was fabricated out of back to back angle to simulate the top chord of an open web steel joist. Varied test parameters include: steel deck profile, …

Evaluation of deck fasteners functioning as shear connectors for composite steel joists
The use of deck fasteners as shear connectors for composite open web steel joists is studied. Results of thirty-six push-off tests are evaluated in terms of strength and behavior. Six types of deck fasteners are considered. They are: 1. #12-24 Teks/5 self-drilling, self-tapping screws. 2. 1/4-14 …

HEADED STUD SHEAR CONNECTORS IN FULL-SIZE COMPOSITE BEAMS WITH WIDE RIBBED METAL DECK
… investigation of the behavior of headed stud shear connectors embedded in slabs with wide ribbed metal deck oriented parallel to the beam. The test program involved the testing of 60 push-out specimens and 4 full-size beam specimens. The main objectives of this investigation were to evaluate …

Fatigue Performance and Shear Demand Distributions of Clustered Shear Connectors in Composite Bridge Girders
… (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 demand distribution may be …

Design and Behavior of Composite Steel-Concrete Flexural Members with a Focus on Shear Connectors
… members. The first part deals with a new type of shear connection in composite joists. Composite steel-concrete flexural members have increasingly become popular in design and construction of floor systems, structural frames, and bridges. A particularly popular system features composite trusses …

Vibration based performance assessment of concrete-concrete composite bridges
… cast in-situ slab are commonly connected using shear connectors. Failure of these connectors would compromise the composite action of the structure, thus reducing the load carrying capacity and hence its efficiency. This study seeks to assess the integrity of such shear connectors using dynamic …

Dynamic performance of pre-cast prestressed beams – cast in-situ slab composite bridges
… in inaccessible parts of the structure such as shear connectors in concrete composite bridges remain undetected until catastrophic failure occurs. Localized non-destructive techniques such as ultrasonic techniques, radar method, impact testing, magnetic based methods and proof load tests are …

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 …

Finite element modelling of shear connection for steel-concrete composite girders
… 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 material …

Strength and Performance of Fiber-Reinforced Concrete Composite Slabs
… under uniform load, the strength of two types of shear connectors used with composite beams and joists, composite slab strength due to a concentrated load, and the flexural toughness and first-crack strength of fiber-reinforced concrete using ASTM C1018 (1998) standard test. The performance 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 …
