| 摘 要： | 通过3根未腐蚀和12根腐蚀钢筋混凝土梁的抗弯试验,研究重复荷载下钢筋腐蚀率对钢筋混凝土梁变形、裂缝、承载力及破坏机理的影响。根据实验数据得出混凝土梁承载力随钢筋腐蚀率的变化规律。同时拟合出钢筋腐蚀率对钢筋与混凝土协同工作系数的影响,提出了受腐蚀梁在重复荷载下的抗弯承载力计算公式。

| Abstract: | The effect of steel corrosion on reinforced concrete beam was studied regarding the deformation, cracking, beating capacity and the failure mechanism of the beam under repeated loading. Fifteen samples, including 3 tmcorroded and 12 corroded reinforced concrete beams were tested. The relationship between the beating capacity of the beam and the corrosion level was presented based on the results. The effect of corrosion level on the coordination coefficient between concrete and the steel reinforcement was presented. The formula for calculating the bearing capacity of corroded beams under repeated loading was suggested. |
