Behavior of beams with dowel action

Engineering Structures, 2007
The 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 ...

Size-dependent response of dowel action in R.C. members

Engineering Structures, 2007
Abstract 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.

Influence of steel fibers on the dowel action of RC beams without stirrups

Engineering Structures, 2020
Abstract 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.

Shear contribution of flange dowel action in steel–concrete–steel​ composite structures

Thin-Walled Structures, 2021
Abstract The shear contribution of flange dowel action in steel–concrete–steel composite structures is studied in this paper. Tests on the shear behaviour of beam-type specimens are carried out, to complement existing experimental results, with particular focus on investigating the influence of flange thickness.

Experimental Investigation of Dowel Action in RC Beams without shear reinforcement

, 2020
The shear failure mechanism of reinforced concrete beams has been studied intensively for the last decades and there is a general agreement that the failure involves several shear transferring mechanisms, including aggregate interlock, shear carrying mechanism of the uncracked compression zone and dowel action.

Modeling dowel action of reinforcement bars for finite element analysis of concrete structures

Computers and Structures, 2001

Analysis of Dowel Action

Journal of the Structural Division, 1971
The shear capacity of the longitudinal reinforcement in concrete beams acting as a dowel across a diagonal tension crack is analyzed, based upon the concept of a beam on an elastic foundation. Axial tension in the dowel, action of the stirrups and progressive horizontal cracking of the cover are included in the analysis.
