The paper investigates the influence of transverse reinforcement on bond strength of splices. It presents an equation to calculate the bond strength of splices confined and not confined by transverse reinforcement. The equation is given for normal strength and high strength concrete (HSC). 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 0.1 O.
These values indicate a significant
improvement in the prediction of the bond strength when compared them with the values obtained from other models. The comparison of the calculated values with HSC test results shows that the equation can also be used for the case of HSC with a good accuracy.
