摘要:
既有结构构件承载能力评定的基本方法应与目前可靠度的控制方法一致，以度量结构可靠性的可靠指标为评定指标，以可靠指标表达的分级标准为判定标准，并以其为基础建立以抗力与荷载效应比表达的实用分级标准.现行国家标准《工业建筑可靠性鉴定标准》GB 50144-2008和《民用建筑可靠性鉴定标准》GB 50292-2015中均提出了构件承载能力评定的实用分级标准和相应的可靠度控制水平，但两者之间存在一定的差异.综合考虑我国在构件可靠度控制方面的经验和现状，提出较为稳妥的可靠指标分级标准，并据此通过可靠度分析提出相应的实用分级标准，可为国家标准的修订提供参考.
Abstract:
The fundamental carrying capacity assessment method of existing structural members should be in accordance with that of present reliability control, taking reliability index measuring structural reliability as assessment index, and taking grading standard expressed by reliability index as judgment standard. On this basis, the practical grading standard is established expressed by ratio of resistantence to load effect. In current national standards “Standard for Appraisal of Reliability of Industrial Buildings and Structures” GB 50144-2008 and “Standard for Appraiser of Reliability of Civil Buildings” GB 50292-2015, the practical grading standard and corresponding reliability control level are both presented, but they are different in some extent. Taking account of the experience and status of reliability control in our country, a sound reliability index grading standard is presented, and the corresponding practical grading standard is put forward by reliability analysis on this basis, which could be taken as a reference for national standard revision.
