Abstract:
To study the damage characteristics and failure mechanism of reinforced concrete (RC)-damaged beams under cyclic load, the loadstrain curve and stiffness-degradation curve of RC beams were
strengthened by adding stirrups. Longitudinal reinforcement and
high-ductile concrete (HDC) under repeated load were compared,
as well as the flexural ability before and after strengthening. The
results show that, compared with the original beam, the strengthening method with longitudinal strengthening at the bottom of the beam has the most obvious improvement in the flexural capacity of the beam. When the longitudinal strengthening is added, the flexural capacity can be increased by 86.25%. According to the actual failure mode of the reinforced beam, the stress-reduction coefficient and height-reduction coefficient are theoretically derived, and the bending capacity of the reinforced beam under each strengthening method is calculated. The theoretical value is in good agreement with the test value.
