Abstract:
Through the pull-out test of 72 HRB500 steel bar bonding and anchoring specimens, the bonding and anchoring performance of HRB500 steel bar was studied. On the basis of the test, the calculation formula of HRB500 steel bar bonding strength is given, and the anchorage length design suggestions of HRB500 reinforced concrete members are proposed on the basis of reliability analysis. The results show that the bonding and anchoring performance of HRB500 steel bar is the same as that of ordinary crescent rib steel bar, and its bonding performance increases with the increase of concrete strength. When c/d <4.5, the bonding strength increases with the increase of protection thickness and decreases with the increase of anchorage length. The anchorage length can be calculated according to the formula specified in the current < concrete structure design code > (GB50010-2002).
