| 摘 要： | 在腐蚀介质作用下，钢筋混凝土梁的抗剪能力会逐步衰减。针对大气环境下的钢筋混凝土梁，提出了基于抗剪承载力随时间变化的在役钢筋混凝土梁抗剪可靠度的预估方法，并进行了实例分析和计算，可为在役钢筋混凝土结构耐久性评估及维修决策提供理论依据。

| Abstract: | Under the action of corroding material, the shear-bearing capacity of reinforced concrete beam will deteriorate gradually. In this paper, the prediction method on anti-shear reliability of existing reinforced concrete beam in atmosphere environment is presented based on deteriorating of its shear behavior, and an illustration example is given. The prediction method can be used to appraising the durability of existing concrete structures and deciding that existing concrete members should be maintained or not. |
