The invention discloses a testing method for testing steel bar-concrete bonding and slipping performance. The testing method comprises the following steps: carrying out a testing design according to astress moment theory; determining a loading method, a section size of a test piece and a production method of the test piece; determining a load-deflection curve and calculating steel bar slipping strain, bonding stress, maximum slipping amount and bonding strength; then identifying a damage mode and processing a testing result. According to the testing method, measured bonding-slipping characteristic parameters eliminate influences, caused by various factors of the testing method, on the testing result; the bonding strength is close to the tensile strength of concrete; the testing method hasgood repeatability and stability. The testing method can be used for researching the bonding and slipping performance of concrete with different types and different strengths, and steel bar-concretewith different types; the testing cost is low and the testing precision is high; abundant results are obtained, and the testing method has a remarkable effect on structure analysis, design and new finding of steel reinforced concrete.
