摘　　要：对横肋对称和非对称钢筋粘结锚固试件进行拉拔试验,研究了横肋对称和非对称钢筋的粘结锚固性能。研究表明,混凝土强度以及锚固长度对于横肋对称与非对称钢筋的粘结锚固强度的影响基本相同。横肋对称和非对称钢筋的粘结锚固强度基本相同,粘结锚固应力-滑移曲线(-τ--s)并无明显差异。Based on the transverse ribs distributed symmetrically and unsymmetrlcally rebar pull-out test, the bondanchorage properties of the transverse ribs distributed symmetrically and unsymmetrically rebar have been investigated. The results show that： the conditions of anchorage, concrete strength and anchorage length are the same effects to bondanchorage strength of the transverse ribs distributed symmetrically and unsymmetrically rebar. The bond-anchorage strength of the transverse ribs distribute symmetrically and unsymmetrically rebar is about the same, anchorage stress-ship curve（^-τ-^-s） haven＇ t the prominent difference.
