Abstract
The bond stresses on longitudinal reinforcement are investigated by determining the ehanges of the bending moment in a short length of the beam. The change of moment produces a corresponding change of tension in reinforcement and the change of tension is a measure of the bond stress. But the actual tensile stresses in reinforcement are not obtained by the usual analysis of stress in a.r.e. beam. The tests reported herein were undertaken with a view to determin the exact stress developed in reinforcement at frequent intervals throughout the span length and to investigate the actual distribution of bond stresses along the reinforcement.
