The efficiency of dowel action in shear transfer in cracked reinforced concrete structures depends strongly n the confinement exerted by the surrounding concrete, as well as on the hoop action of the stirrups. In spite of the many test data obtained to date in this field, several aspects of dowel behavior are still open to further investigation, since dowel/cover/stirrup interaction is a manifold problem, especially when the dowel bar pushes against a thin concrete cover. Within this framework, 28 reinforced concrete specimens reinforced with a single deformed bar 14, 18, and 24 mm in diameter (#5,6, and 8) were tested as a part of a major research program on dowel action. Block-type specimens were loaded according to a displacement-controlled procedure.

Abstract

The efficiency of dowel action in shear transfer in cracked reinforced concrete structures depends strongly n the confinement exerted by the surrounding concrete, as well as on the hoop action of the stirrups. In spite of the many test data obtained to date in this field, several aspects of dowel behavior are still open to further investigation, since dowel/cover/stirrup interaction is a manifold problem, especially when the dowel bar pushes against a thin concrete cover. Within this framework, 28 reinforced concrete specimens reinforced with a single deformed bar 14, 18, and 24 mm in diameter (#5,6, and 8) were tested as a part of a major research program on dowel action. Block-type specimens were loaded according to a displacement-controlled procedure.
