摘要

摘要: 分别对中、美、欧的砌体结构设计规范和鉴定标准进行了对比分析。结果表明:美国鉴定标准中不进行强度折减,欧洲鉴定标准明确了分项系数调整方法;在抗震鉴定中,美、欧标准均采用了基于性能的抗震鉴定方法,抗震鉴定过程中考虑了认知水平的影响,调整了重力荷载代表值和抗震承载力的计算方法;中国规范中,鉴定与设计承载力极限状态方程相同,对既有建筑结构安全性鉴定来说偏保守。建议今后相关鉴定标准修订时,可引入基于性能的鉴定方法,并通过可靠性理论对承载力极限状态方程的分项系数进行修正。

Abstract: The design and assessment standards of masonry structures in China, the US and Europe were briefly compared. The results showed that the US standard did not reduce the strength, and the European standard defined the adjustment method of partial coefficients. In the seismic assessment, the US and European standards adopted performance-based assessment methods, considering the influence of cognitive level, the representative values of gravity load and the calculation method of seismic bearing capacity were adjusted. The ultimate limit state function of bearing capacity in Chinese assessment and design standards were the same, which was conservative for the safety assessment of existing building structures. It was suggested to introduce the performance-based methods in the future revision of the Chinese assessment standards and modify the partial factors of the ultimate expression of bearing capacity according to the reliability theory.
