摘　　要：通过对 72个HRB5 0 0钢筋粘结锚固试件的拉拔试验 ,分析了HRB5 0 0钢筋的粘结锚固特点和影响粘结锚固强度的主要因素 ,在统计回归的基础上给出了HRB5 0 0钢筋粘结强度的计算公式 ,推导出HRB5 0 0钢筋的临界锚固长度计算公式 ,最后在可靠度分析的基础上提出了HRB5 0 0钢筋混凝土构件的锚固长度设计建议。Based on 72 HRB500 steel bar specimens pull-out tests,it is investigated that the bond-anchorage properties of HRB500 steel bar s and the main factors influencing the bond capacity between HRB500 steel bars a nd concrete.Then the calculating formula of bond length has been established thr ough statistical regression,and the formula on critical anchoring length of HRB5 00 steel bars is also deduced.In the end,the design of anchoring length by way o f reliability analysis of HRB500 steel bars concrete elements are proposed.
