Lateral reinforcements contribute to confinement of main reinforcements, increase bond splitting strength and improve brittle failure. To make clear the correlation between local bond splitting behavior with confinement of lateral reinforcement in RC members, it is necessary to quantify effect of lateral confinement in bond splitting behavior. To obtain the local bond stress versus slippage relationship with confinement of lateral reinforcement, pull-out bond test is conducted. The test results show that maximum bond stress has an increment as lateral confinement stress also increases, and the slippage at maximum bond stress is influenced by splitting crack width and shape of main reinforcement. A new relationship between bond stress and slippage in case of confinement of lateral reinforcement is proposed using these results and effect of lateral confinement. A numerical analysis is performed to confirm the model with experimental results. The analytical results show a good agreement in bond splitting strength with experimental results of previous studies.
