Influence of transverse reinforcement on bond strength of tensile splices

Abstract The influence of transverse reinforcement on bond strength of tensile splices is investigated. An equation to calculate the bond strength of splices confined and not confined by transverse reinforcement is presented. The equation which covers all grades of concrete shows good correlation with test results. For instance for 138 normal strength concrete test results reported in the literature the mean value of test/calculated bond strength is 1.00 with a standard deviation of 0.10. These values indicate a significant improvement in the prediction of the bond strength when compared to the values obtained from other models.
