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 …

Elastic-plastic finite element modeling of long span composite joists with incomplete interaction
… by modeling the nonlinear behavior of the steel shear connectors. Experimental tests on long span composite open-web steel joists were performed at Virginia Polytechnic Institute and State University. Measurements of joist deflections, member strains, and slip between the concrete slab and steel …

Analytical investigation of composite diaphragms strength and behavior
… beam size and orientation, panel dimension, connector type and distance, slab opening, yield plateau, and beam connection flexibility. Shear connector, deck-to-concrete interface, and beam connection were the components modeled non-linearly. Orthotropic behavior was used for the deck …

Strength Calculation Model for Standoff Screws in Composite Joists
… procedure that would allow the use of this shear connector in design of composite floor systems. The study considers results from push-out tests using this type of screw reported by Hankins et al. (1994), Alander et al. (1998), Webler et al. (2000), and Mujagic et al. (2000). Further, this …

Strength of welded shear studs
… were conducted to study the behavior of welded shear studs. Forty-eight solid slab push-out tests were conducted to study how stud tensile strength and concrete properties affect the strength of shear connections. It is shown that raising the tensile strength of a shear connector actually has an …

Horizontal Shear Transfer for Full-Depth Precast Concrete Bridge Deck Panels
… their full composite strength, the horizontal shear resistance provided at the slab-to-beam interface must be quantified through further investigation. Currently, all design equations, both in the AASHTO Specifications and the ACI code, are based upon research for cast-in-place slabs. The …

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, …

The mechanics of plastic-aluminum composite I-beams
… The I-beams investigated here use an internal shear connector (deboss) which acts as a mechanical fastener between the aluminum and the flange plastic. A numerical finite element model was developed in ABAQUS to better understand the underlying physics of the deboss and was compared with a …

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 …
