[摘要]在对我国各阶段设计规范的可靠度水平比较基础上,回顾了我国工业建筑可靠性鉴定分级标准的发展。2014年修订《工业建筑可靠性鉴定标准》(GB 50144—2008)过程中,在总结我国两代《工业建筑可靠性鉴定标准》分级原则的基础上,提出了基于可靠度理论的可靠指标分级标准和与之适应的抗力荷载效应之比分级标准。新修订的《工业建筑可靠性鉴定标准》(GB 50144—201X)在可靠指标分级标准和抗力荷载效应之比分级标准方面保持了连续性,适应新的设计规范可靠度水平的提高,更加符合建筑的实际情况。

Abstract:On the basis of comparing the reliability levels of design codes at different stages in China, the development of reliability appraisal and grading standards for industrial buildings in China was reviewed. In the revision of Standard for reliability appraisal of industrial buildings and structures(GB 50144—2008) in 2014, on the basis of summarizing the grading principles of two generations of Standard for reliability appraisal of industrial buildings and structures in China, the grading standards of reliability indexes based on reliability theory and the corresponding grading standards of resistance load effect were put forward. The newly revised Standard for reliability appraisal of industrial buildings and structures(GB 50144—201X) maintains continuity in terms of reliability index grading standards and resistance load effect grading standards, adapts to the improvement of reliability level of new design codes, and is more in line with the actual situation of buildings.

Keywords:industrial building; standard comporison; reliability appraisal; reliability index; grading criteria
