《公路工程结构可靠度设计统一标准》(GB/T50283-1999)的批准颁发,标志着我国工程结构设计将全面转向以概率可靠度理论为基础的可靠性设计方法上来。结构的设计基准期是结构可靠度理论的一个基本概念,但是目前工程界对这一时间概念仍然十分含混。本文以可靠度设计为核心,探讨设计基准期在结构可靠度设计中的作用,以及它与其他几个时间概念之间的关系,并对今后可靠度设计理论在工程界的推广应用提出一点建议。
The approval and promulgation of “Unified Standard for Reliability Design of Highway Engineering” (GB / T50283-1999) indicates that the engineering design of our country will be completely shifted to the reliability design method based on the theory of probability reliability. The design base period of a structure is a basic concept of structural reliability theory, but the current engineering concept of the time is still very vague. In this paper, the reliability of the design as the core, to explore the design of the reference period in the structural reliability of the role and its relationship with several other concepts of time, and the reliability of the design theory in the field of engineering popularization and application put forward some suggestions .
