Ni-Ti合金绞线与混凝土之间的粘结和锚固是二者能够协同工作的基础,Ni-Ti合金绞线与混凝土的粘结-滑移本构关系模型是其粘结锚固性能的综合反映.对64个试件进行单端拉拔试验,测定试件的粘结滑移曲线.结果表明:通过对其粘结破坏特征、粘结滑移机理及受力过程的分析,提出了一种新的粘结滑移本构关系模型,能较好地反映Ni-Ti合金绞线与混凝土的受力全过程,与试验结果吻合良好.
The bonding and anchoring between Ni-Ti alloy stranded wire and concrete are the foundation for their mutual cooperation. The bond-slip constitutive model of Ni-Ti alloy stranded wire and concrete is the combination of its anchoring and anchoring properties The test results show that the bonding slip characteristics of the bond, the mechanism of the bond slip and the analysis of the process of the stress are put forward The new model of the bond-slip constitutive model can well reflect the whole process of the stress of Ni-Ti alloy stranded wire and concrete, which is in good agreement with the test results.
