To clarify the load-carrying behavior change of RC beam caused by the expansion of concrete, the fracture of reinforcement or the expansive crack along the longitudinal reinforcement, experimental study was carried out. From the experimental investigation, the shear resistance and structural deformation were highly influenced by fractured stirrups. However, in case of no expansive crack, the effect of the fractured longitudinal reinforcement to the load-carrying behavior was not obvious. Moreover, the effect of expansive crack to the increase of deformation capacity was observed. |
