AbstractThe bond performance of mortar anchor under dynamic load was simulated by dynamic pull-out test of steel bar. The influence of the loading rate, anchoring length and mortar strength on the bond performance was analyzed. The results showed that with the increase of the loading rate, the peak of bond stress increased gradually and the rising part of the bond stress curve changed rapidly. Meanwhile, the strain of the steel along the anchoring depth gradually decreased and the decreasing rate increased gradually. With the increase of the anchoring length, the sum of the bond stress at each point in the anchoring section increased gradually and the bond performance improved. With the increase of the mortar strength, the peak of the bond stress curve moved toward the loading end and the distance transferred by the bond stress along the anchoring depth was small.
