摘要：
The bending fatigue damage characteristic of carbon and polypropylene hybrid fiber reinforced concrete (C-P HFRC) was studied in detail. An experiment was designed to obtain the law on the alteration of the C-P HFRC's fatigue life and fatigue strength caused by the fibers. Fatigue equation S= A-BlgN was obtained through the linear regression. The C-P HFRC's bending fatigue damage characteristic was carried out. The composition and development of the fatigue strain caused by the cyclic load were analyzed on the basis of experimental results, and the bending fatigue strain mode was supposed. The law of the fatigue damage accumulation and evolution under cyclic load was investigated. The fatigue damage model was established.
