Mechanical Performance and Contact Zone of Timber Joint With Oblique Faces

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2015
The goal of the work was to evaluate mechanical performance of full-scale timber beams containing scarf joint with a dowel. Work focused on standard testing using modular system to obtain effective stiffness and strength of the beams with and without the

The influences of the number of concrete dowels to shear resistance based on push out tests

open access: yesFracture and Structural Integrity, 2022
To reduce the depth of floor-beam structures and to save the cost of headed-shear studs, many types of shallow composite beam have been developed during the last few years. Among them, the shallow-hollow steel beam consists of web openings, infilled with

Numerically efficient mechanical modeling of reinforced concrete membrane elements with fixed, interlocked cracks

open access: yesStructural Concrete, EarlyView.
Abstract Compression field approaches such as the Cracked Membrane Model with fixed, interlocked cracks (CMM‐F) are efficient tools for the mechanical modeling of reinforced concrete elements, providing the mechanical model σ=fε$$ \boldsymbol{\upsigma} =f\left(\boldsymbol{\upvarepsilon} \right) $$ required for finite element analyses.

Mechanics‐based model for cold joints in reinforced concrete members

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces a mechanics‐based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading. The model incorporates mechanisms such as interface slip and opening, aggregate interlock, clamping force, and dowel action of the reinforcing bars crossing the interface.

Shear transfer between precast prestressed bridge beams and in-situ concrete crosshead in continuous structures [PDF]

open access: yes, 1988
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 ...

Effectiveness of Dowels in Concrete Pavement [PDF]

open access: yesMaterials, 2019
Dowels are located in transverse joints of Jointed Plain Concrete Pavements (JPCP) and they are used to provide load transfer between individual slabs, reduce faulting and improve performance. Dowels and the concrete itself are under the highest stress in the vicinity of joints; thus, in terms of pavement design, the joints are the weakest points of ...

Simple and detailed modeling of corrosion‐affected slender shear critical RC beams

open access: yesStructural Concrete, EarlyView.
Abstract The corrosion of steel bars compromises both the safety and the serviceability of reinforced concrete (RC) structures. Consequently, reliable tools are required to estimate the detrimental effects of corrosion on the structural response of RC members subjected to transverse loads.

Kinematics‐based model for shear capacity assessment of unreinforced interior beam–column joints

open access: yesStructural Concrete, EarlyView.
Abstract This study presents a kinematics‐based model for assessing the shear strength of reinforced concrete interior beam–column joints without transverse reinforcement. The proposed framework is built on first principles—kinematics, equilibrium, and constitutive relations—and explicitly models discrete cracks by introducing kinematic parameters such

Predicting Behavior of Grouted Dowel Connections Using Interfacial Cohesive Elements

open access: yesApplied Sciences, 2019
Grouted dowel connections are used extensively in precast load bearing walls owing to their simple construction and forgiving tolerances. Current design guidelines do not adequately consider the composite nature of such connections.
