摘要
将纤维聚合物筋锚杆与锚固体之间的粘结层简化为粘结界面,以纤维聚合物筋锚杆、锚固体的应力应变本构关系以及纤维聚合物筋锚杆与锚固体的非线形粘结滑移本构关系为基础,利用数值叠代和递推计算方法实现了纤维聚合物筋锚杆与锚固体锚固性能的计算机模拟试验,并以纤维聚合物筋与混凝土的粘结锚固问题为例进行了数值分析,得到了纤维增强塑料筋与混凝土的加载端拔出力与滑移的关系.
The bond layer between the tendon and the fixed anchor length is simplified into the bond interface in this paper.On the basis of the constitutive models for FRP tendon,fixed anchor length and bond slip relationship between the tendon and the fixed anchor length,the nonlinear and whole-process numerical analytical method is used to study the behavior of bond between the tendon and the fixed anchor length.The bond of FRP rebar to concrete is used to simulate the bond of the tendon and the fixed anchor length,and the force-slip curve in the loading end is gained.
