摘　　要：从承载力角度出发,综合考虑了外部环境以及混凝土本身影响因素,利用工程中实际能检测到的数据,推导出在役钢筋混凝土梁斜截面抗剪承载力剩余寿命的公式。并通过结构可靠度理论对构件的剩余寿命做了进一步的校核。This article from the capacity point of view,considering the external environment as well as the concrete itself,the impact of factors,the actual use of project data can be detected,derived from in-service oblique cross-section of reinforced concrete beam shear strength of the residual life of the formula.Structural reliability theory through the remaining life of the components to do further checking.
