［摘要］在對我國各階段設(shè)計(jì)規(guī)范的可靠度水平比較基礎(chǔ)上，回顧了我國工業(yè)建筑可靠性鑒定分級標(biāo)準(zhǔn)的發(fā)展。2014年修訂《工業(yè)建筑可靠性鑒定標(biāo)準(zhǔn)》（GB 50144—2008）過程中，在總結(jié)我國兩代《工業(yè)建筑可靠性鑒定標(biāo)準(zhǔn)》分級原則的基礎(chǔ)上，提出了基于可靠度理論的可靠指標(biāo)分級標(biāo)準(zhǔn)和與之適應(yīng)的抗力荷載效應(yīng)之比分級標(biāo)準(zhǔn)。新修訂的《工業(yè)建筑可靠性鑒定標(biāo)準(zhǔn)》（GB 50144—201X）在可靠指標(biāo)分級標(biāo)準(zhǔn)和抗力荷載效應(yīng)之比分級標(biāo)準(zhǔn)方面保持了連續(xù)性，適應(yīng)新的設(shè)計(jì)規(guī)范可靠度水平的提高，更加符合建筑的實(shí)際情況。

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
