摘要
本文采用一次二阶矩的近似概率法,对现行《水工钢筋混凝土结构设计规范(SDJ20—78)》中的构件强度可靠度进行了校准计算和分析,提出了水工混凝土结构设计目标可靠指标的取值建议,可供《水利水电工程结构可靠度设计统一标准》的编制和《水工混凝土结构设计规范》修订时参考。
The approximate probability design method of the first-order, second-moment is adopted for calibrating and analysising the reliability of members strength in 《Design Cede of Reinforced Concrete of Hydrostructures(SDJ20—78)》. The short-cut process proposal of target reliability indices for design of concrete of hydro-structures is presented. These research achievements provide a scientific basis for the compilation of 《Unified Standard for Reliability Design of Hydro-structures》 and the revision of 《Design Code of Concrete of Hydro-structures》.
