| 要旨 | A procedure for predicting the fatigue life of reinforced concrete members is proposed. An analytical model for reinforced concrete (RC) and reinforced steel-fiber-concrete (RSFC) beams without stirrups is developed based on FEM with discrete crack concept. The mechanical degradation of materials under fatigue load is considered as a major factor for fatigue crack propagation and subsequent fracture. The results from the ahalysis show that fibers can improve fatigue resistance of RC beams by extending fatigue life and changing the failure mode from shear to flexure. It also reveals that fiber-concrete could be applied for the repair of structures subjeted to fatigue load. |
