摘　　要：本文依据６根无箍筋和１２根有箍筋梁正截面受弯的对比试验，研究了箍筋的约束对梁正截面破坏形态、混凝土极限压应变、梁挠度和受弯承载力的影响，并提出约束混凝土梁受弯承载力增强公式。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.
