在概述了容许应力法的基础上,简单介绍了可靠度的基本概念,分析了桥梁结构上作用的概率模型和结构构件抗力的统计特征,最后对《公路工程结构可靠度设计统一标准》(GB/T50283-1999)中极限状态设计表达式中系数的取值做了简单探讨。
On the basis of an overview of the permissible stress method, the basic concept of reliability is briefly introduced. The probability model of the bridge structure and the statistical characteristics of the structural members’ resistance are analyzed. Finally, the unified standards for the reliability design of the highway engineering structure (GB / T50283-1999) in the limit state design expression of the value of a simple discussion.
