Before revision: Mechanism of composite action of reinforcement and concrete The reinforcement in a RC structure, such as a steel bar, has to undergo the same strain or deformation as the surrounding concrete in order to prevent discontinuity, slip or separation of the two materials under load.
After revision: Mechanism of composite action of reinforcement and concrete The reinforcement in a RC structure, such as a steel bar, has nothing to do with the anchrundergo the same strain or deformation as the surrounding concrete in order to prevent discontinuity, slip or separation of the two materials under load.
