摘要:
通过对72个HRB500钢筋粘结锚固试件的拉拔试验,研究HRB500钢筋的粘结锚固性能.在试验的基础上给出了HRB500钢筋粘结强度的计算公式,并在可靠度分析的基础上提出了HRB500钢筋混凝土构件的锚固长度设计建议.研究表明:HRB500钢筋的粘结锚固性能与普通月牙肋钢筋相同,其粘结性能随混凝土的强度提高而提高;当c/d＜4.5,粘结强度随保护厚度的增大而增大,随锚固长度的增加而降低.锚固长度可按现行<混凝土结构设计规范>(GB50010-2002)的规定公式计算.
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).
