| Abstract: | On the basis of tests on flexural performance in normal sections of 6 beams without stirrup and 12 beams with stirrups,the effects of stirrup confinement on the failure patterns in normal section of beams, the ultimate compression strain, the deflection and the flexural strength of beams are studied. The formula for calculating the enhanced flexural strength of confined concrete beams is proposed. |

| Keywords: | closed stirrup confined concrete reinforcement ratio stirrup ratio bending normal section |
