Horizontal Shear Transfer Between Ultra High Performance Concrete And Lightweight Concrete
… to carry larger loads. As the forces being transferred through composite members are increasing in magnitude, it is vital that the equations being used for design are applicable for use with the new materials. Of particular importance is the design of the horizontal shear reinforcement …

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 …

Experimental and analytical study of the shear transfer in composite shallow cellular floor beams
This research investigated the longitudinal shear transfer mechanism in composite shallow cellular floor beams. The shear transfer mechanism is different with the headed shear studs used in composite construction. The shear resisting properties and behaviour of the shear transfer mechanism has not …

Shear transfer between precast prestressed bridge beams and in-situ concrete crosshead in continuous structures
A detailed investigation was made to study the shear transfer between precast prestressed beams and in-situ concrete in a relatively new method of construction of continuous bridge decks where the ends of precast beams are connected to an integral in-situ crosshead away from the supports. Two …

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 …

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 …

Evaluation of lateral strength and deflection for unreinforced masonry cracked walls
… cracked behavior is considered by neglecting the shear transfer across the cracked masonry. Based on the developed shear and normal stress distributions with cracking, the possible failure modes in an unreinforced masonry wall are examined. Some failure criteria are directly related to the results …

Machine Learning Prediction of Shear Capacity of Steel Fiber Reinforced Concrete
… growing in recent years owing to the improved shear strength and post-cracking toughness imparted by fiber inclusion. Yet, there is still lack of design provisions for steel fiber-reinforced concrete (SFRC) in building codes. This is mainly due to the complex shear transfer mechanism in SFRC. …

Ultimate strength analysis of partially composite and fully composite open-web steel joists
… composite steel joists with various degrees of shear connection is investigated. The results of eight full-size composite joist tests, conducted as a portion of the study, are presented. Joist spans range from 24 ft. to 30 ft. and depths from 8 in. to 18 in. Six types of mechanical connectors …

Characterization of Concrete Pavement Joint Surfaces
… structures especially pavements, the ability to transfer shear load across crack/joint and the cracking resistance are important. This research was conducted in order to develop a testing method and roughness parameter that could better predict the shear load transfer across crack/joint. In …

Machine Learning Based Prediction of Reinforced Concrete Members’ Shear Friction Capacity
Shear friction theory describes the mechanisms by which shear forces are transferred across concrete-to-concrete interfaces. Shear transfer across a plane involves a complex interaction of several phenomena, such as concrete surface condition and cohesion, concrete strength, and steel reinforcement …

Two-Direction Cracking Shear-Friction Membrane Model for Finite Elment Analysis of Reinforced concrete
… cracked reinforced concrete that provide reduced shear stiffness but do not limit shear strength. In addition typical models are not based on the actual physical behavior of shear transfer across cracks by shear friction recognized in the ACI Building Code and present in previous experimental …

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. …

Precast Full-Depth Deck Panels Supported on Inverted Bulb-Tee Bridge Girders
… middle panel transverse joints to maximize the shear transfer. Stiffness tests were performed at every 50,000 load cycle interval for both fatigue tests. No significant damage in addition to the shrinkage cracks was observed through the entire fatigue test, and the overall bridge stiffness did …

Shear Behaviour in Slender Reinforced Concrete Beams with and without Transverse Reinforcement
This study investigates shear crack behaviour in slender reinforced concrete (RC) beams, focusing on the critical shear crack (CSC) geometry and its impact on crack kinematics and shear transfer mechanisms. Existing models often oversimplify CSC shape assumptions, potentially leading to …

Longitudinal shear resistance of steel and concrete composite beams
In this study the longitudinal shear resistance of steel and concrete composite beams using conventional headed stud connectors has been investigated through the testing of 42 push-out specimens. In addition, the applicability of the existing design codes and the standard specimen used in assessing …
