摘要
通过拉拔试验,研究了不同的钢筋直径和锚固长度对钢筋与自密实混凝土粘结锚固性能的影响,应用损伤理论,建立了考虑界面损伤的钢筋与自密实混凝土的粘结滑移关系式,理论计算与试验结果吻合较好,并根据试验数据,得到了C40自密实混凝土的受拉钢筋基本锚固长度设计建议值。
Through the pullout test,this paper researched the application of different bar diameter and anchorage length to bar and self-compacting concrete bond anchorage performance,applied the damage theory,established the bond-slip amount relation of bar and self-compacting concrete considering interface damage,the theoretical calculation and test results in good agreement,and according to the test data,obtained the tensile bar basic anchorage length design suggestion values of C40 self-compacting concrete.
