To clarify the load-carrying behavior of RC beams caused by the rebar fracture and the expansive crack along the longitudinal reinforcement due to aggregate expansion simulating ASR, experimental study was carried out. From the test result, all specimens caused by the rebar fracture failed in shear tension. Moreover, cracking behavior and crack propagation highly influenced by the range of expansive crack.
