Mechanical modeling of dowel action and the influence of small amounts of shear reinforcement on the shear‐transfer actions in <scp>RC</scp> beams

Dowel action of the longitudinal reinforcement in RC beams without and with small amounts shear is typically considered a constant contribution determined from splitting strength concrete cover. However, recent experimental investigation by authors, it was shown that force transferred dowel for should be displacement linear elastic model rigid plastic model. This article aimed at extending this to also cover members reinforcement. To aim, novel approach calculate carried both presented. The derived establishing an equilibrium work between internal stored or dissipated energy external performed dowel. Additionally, method determine DIC measurements For remaining shear-transfer actions, reasonable constitutive models literature are adapted. On basis measurements, each actions calculated 16 tests sum predict applied fairly well, development critical crack until failure. below minimum requirements according current design standards, capacity governed aggregate interlock, residual tensile stresses, inclination compression chord. While above requirements, action.
