Dowel Action of Titanium Bars Connecting Marble Fragments
The Masonry Society Journal, 2006In conservation of monuments of classical antiquity, titanium bars are quite often used to connect fragmented marble members. An experimental program was carried out with the aim of investigating the behavior of titanium bars inserted in marble and subjected to shear.

Size-dependent response of dowel action in R.C. members
Engineering Structures, 2007Abstract Experimental investigations on concrete indicate that for the same specimen geometry, the nominal strength of the specimen decreases with increasing specimen size. This phenomenon is called the size effect in fracture mechanics of concrete/reinforced concrete.

Behavior of beams with dowel action
Engineering Structures, 2007The phenomenon of dowel action as a shear transfer mechanism across cracks has long been recognized as an important component of the overall shear resistance capacity of reinforced concrete beams. In this paper, a simple analytical model for the dowel action of reinforcing bars crossing cracks is developed for analysis of reinforced concrete beams ...

An appraisal of dowel action in reinforced concrete beams
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2013The purported mechanism of dowel action in the shear capacity of longitudinally reinforced concrete beams has been revisited, and the results of an experimental investigation of the effect of bar size and amount of tension reinforcement on the load-carrying capacity of such beams designed to fail in shear are discussed.

A study of dowel action in reinforced concrete beams
Magazine of Concrete Research, 1999This paper reopens the question concerning the contribution of dowel action to the shear capacity of reinforced concrete beams. First, a literature survey on the subject reveals that, despite the implicit belief in much of the current design thinking that dowel action can play a significant role in the mechanism through which shear is carried in a ...

Mathematical models for dowel action under monotonic and cyclic conditions
Magazine of Concrete Research, 1986Synopsis On the basis of physical models describing the behaviour of dowels embedded in concrete, formulae for the prediction of dowel strength under monotonic actions are derived. In addition, formulae for calculating transverse displacements corresponding to the dowel strength are given.

Prediction of Dowel Action against Concrete Core without Consideration of Transverse Reinforcement
Journal of Structural Engineering, 2020AbstractIn this study, reinforcing bars acting as dowels were investigated. Direct shear tests on specimens with a wide range of strengths for concrete (30 and 60 MPa) and steel (400 and 600 MPa) w...

Influence of steel fibers on the dowel action of RC beams without stirrups
Engineering Structures, 2020Abstract Although many researchers have already studied the shear behavior of reinforced concrete (RC) beams, the contribution of each resisting mechanism to the shear capacity is not fully understood. The problem becomes more complicated when steel fibers are added to the concrete, which may affect those mechanisms differently.

Three-dimensional bond model considering the coupled damage effect for dowel action
Magazine of Concrete Research, 2017The behaviour of the dowel action as a shear transfer mechanism across interfaces and joints has been recognised as an important component of structural analysis. In this paper, a three-dimensional non-linear bond model considering the coupled damage effect of concrete was developed to simulate the mechanism of interaction between reinforced bars and ...
