摘要
用微观的方法从理论上研究了公路用混凝土结构增强用及斜拉索用纤维筋棒（ＦＲＰＲｅｂａｒ）的破坏机理，提出了研究纤维应力集中的载荷距离加权局部分配法则和破坏柱元的概念，给出确定柱元长度的方法。在此基础上，用统计理论建立了纤维筋棒的破坏（强度）理论，并用其做了具体实例计算，其计算结果与现有结果一致。
The failure mechanism of FRP rebar used for reinforcement of concrete structures of highway is studied in theory using the microstructure method. The concept of the element of fiber column and the weighting distance local loadsharing rule are presented, and the method of determination of the length of a column element is given in this paper. Based on the above studies, the failure theory of FRP rebars is established using statistical method, and the numerical results obtained from this theory show no difference with the experimental ones.
