DOWEL ACTION BETWEEN TWO CONCRETES
Journal of Engineering, 2009 This paper reports eight tests in which in-plane shear forces are applied across the joint between two different concretes forming a composite action. Shear can be transmitted across the joint either by interlocking of the aggregate particles protruding

Analysis of Dowel Action in Reinforced Concrete Beams with Shear Reinforcement
Civil and Environmental Engineering, 2021 The shear transfer mechanism was examined to view the contributions of different components of shear transfer such as aggregate interlocking, dowel force and uncracked compression zone.

Dowel action of the tensile reinforcement in RC beams without shear reinforcement: Novel experimental investigation and mechanical modelling [PDF]
Engineering Structures, 2023 Dowel action is a well-known phenomenon in shear-related problems within structural concrete. The tests previously reported in the literature to evaluate this contribution in reinforced concrete beams without shear reinforcement were conducted without any initial activation of the tensile reinforcement.This paper presents the experimental results of ...

Nonlinear Bond Model for the Dowel Action considering the Fatigue Damage Effect
Advances in Materials Science and Engineering, 2018 To investigate the mechanical properties of dowel action under fatigue loads, 3 reinforced concrete specimens with different bar diameters (12 mm, 20 mm, and 25 mm) were subjected to the fatigue loading and were designed to investigate the attenuation ...

Modeling of dowel action for cast-in and post-installed anchors considering bond property
Engineering Structures, 2021 application/pdf In reinforced concrete structures, cast-in anchors are applied to beam-column or slab-beam joints. Furthermore, in seismically strengthened structures, post-installed anchors are used to connect new members to existing members. These anchors are subjected to shear and tensile stresses during an earthquake.

Experimental investigation of dowel action in reinforcing bars using refined measurements
Structural ConcreteAbstractIn typical reinforced concrete design, reinforcement is designed to carry axial forces, but it can also resist transversal forces by dowel action. This is usually neglected for simplicity's sake in the design phase, but it can be accounted for either explicitly in mechanical models or implicitly in empirical relationships.

Steel stresses and shear forces in reinforcing bars due to dowel action
Structural ConcreteAbstractReinforcing bars in structural concrete are typically designed to carry axial forces. Nevertheless, due to their bending stiffness, the bars can also carry transverse forces, that are associated with the localized bending mechanism (dowel action) resulting from the relative displacements (or slip) wherever a crack interface or a discontinuity ...

A NEW PREDICTIVE EQUATION FOR PUNCHING SHEAR STRENGTH OF REINFORCED CONCRETE FLAT SLABS BASED ON NUMERICAL PARAMETRIC STUDY [PDF]
European Journal of Materials Science and Engineering, 2023 The paper proposes a new equation for the prediction of punching shear strength of reinforced concrete flat slabs. The basis of the new predictive equation is a detailed numerical parametric study conducted using the nonlinear 3D finite element analysis ...
