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 …

Quantifying the compressive ductility of concrete in RC members through shear friction mechanics.
… in RC members has been quantified through shear friction mechanics. Firstly, the size dependent stress‐strain models for unconfined and actively confined concrete are derived based on the fundamental mechanics of shear friction theory. At this stage, the shear friction properties, that is …

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 …

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 …

Pressure Fluctuations in a High-Reynolds-Number Turbulent Boundary Layer over Rough Surfaces of Different Configurations
… addition, it was proven that the high frequency shear friction velocity scaling of Meyers et al. (2015) is universal to rough surfaces of different element shape and density. Physical insights into the shear friction velocity, on which this scaling is based, have been revealed. This includes 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 …

Analysis of the AASHTO LFRD Horizontal Shear Strength Equation
… in the deck to the girders is done across a shear interface between the two elements. The transfer occurs through the cohesion of the concrete at the interface and then through the shear reinforcement across the interface. Adequate shear strength is essential to the success of the …

Magnetic quartz crystal microbalance
… model attributed the effect to internal shear friction loss among other losses is modulated by the magnetic field. Quantum effect was considered. However, after examining SEM surface images, the source of acoustic response to magnetic field is more likely from interfacial stresses.

Retrofitting of reinforced concrete beams with CFRP straps to enhance shear capacity
… Fibre Reinforced Polymer (CFRP) straps for shear enhancement of reinforced concrete beams. Previous studies using these straps have employed steel pads on top of the beam to support the strap but this is problematic from a practical point of view. The initial goal of this research was to …

Optimum shear strengthening of reinforced concrete beams
… polymer (CFRP) straps can be used to strengthen shear deficient reinforced concrete (RC) structures. The strengthening system is associated with a number of parameters including the number of straps, strap locations, strap stiffness, and strap prestress. The initial goal of this research was to …

Interface Shear Strength in Lightweight Concrete Bridge Girders
… to develop composite action, adequate horizontal shear resistance must be provided at the interface. As lightweight concrete is increasingly being used in bridge designs, it is important to understand the horizontal shear behavior of lightweight concrete. The current AASHTO LRFD Specification …
