| 摘 要： | 对弯、剪、轴拉复合受力状态下钢筋混凝土梁的承载能力进行试验研究。试验中主要考虑轴向拉力、最小抗剪配筋、配筋率、混凝土强度等级等因素对弯、剪、轴拉复合受力状态下钢筋混凝土梁的承载能力的影响。试验实测表明,欧洲规范2第1部分中用于计算弯、剪、轴拉复合受力钢筋混凝土梁承载能力的公式过于保守,有必要进行修正。

| Abstract: | Relatively comprehensive test study on the strength capacity of the reinforced concrete beam under bending moment,shear force and axial tensile force was carried out.The influences of axial tensile force,minimum shear reinforcement,the ratio of reinforcement and the class of concrete were considered.The results show that in Eurocode 2 part 1 the formula,which can be used to calculate the strength capacity of the reinforced concrete beam under the above-mentioned complex mechanical state,is conservative and should be revised. |

| Keywords: | reinforced concrete beam complex mechanical state axial tensile force minimum shear reinforcement strength capacity |
