| 摘 要： | 锈蚀钢筋混凝土深梁的承载力不仅与纵向钢筋的截面损失有关,而且和钢筋与混凝土之间的粘结强度的降低,混凝土保护层中出现的纵向锈胀裂缝有关,本文先考虑了由于钢筋的截面损失引起的钢筋混凝土深梁的抗弯承载力的降低;再在梁-拱共同作用抵抗剪力的机制上,计算了无腹筋锈蚀钢筋混凝土深梁的抗剪承载力,进而提出了无腹筋锈蚀钢筋混凝土深梁的承载力计算公式。

| Abstract: | Load carrying of corroded reinforced concrete(RC)deep beams is related to not only the reduction of steel cross section,but also the reduction of bond strength and the longitudinal cracking in concrete cover due to reinforcement corrosion.the flexural bearing capacity of corroded RC deep beams is calculated by considering the reduction of steel cross section;then the shear bearing capacity of corroded RC deep beams without stirrups is calculated on the basis of a combined resistance of beam action and arch action;and then the formula of the load capacity of corroded RC deep beams without stirrups is suggested. |
