Part of: Composite and Mixed Construction

Abstract: This paper describes an investigation into the bond stress developed between steel shapes and reinforced concrete when the concrete is lightly stressed. A brief discussion of previous research and relevant design specifications is included. Two series of experiments are then described which show that significant bond between the embedded steel shape and reinforced concrete can be achieved without the use of shear connectors. Several parameters which affect the magnitude of the bond stress are studied and the distribution of bond stress before and after slip is noted. A simple design model is postulated and compared to experimental results.
