摘　　要：对国内外的试验资料进行了研究分析 ,对有代表性的砌体抗压强度计算模式不定性进行了比较。结果显示 ,我国砌体设计规范的砌体抗压强度计算模式对于抗压强度较高的烧结普通砖、烧结多孔砖砌体安全储备偏大。并对规范设计计算公式、计算模式不定性的考虑以及公式局部限制条件等提出了补充建议。供我国砌体结构设计与施工规范的修订时参考。Through analysis on the data collected from published experimental results, the uncertainty in several models proposed in the literature for prediction of masonry compressive strength are studied. Furthermore, where possible, models suggested in representative design codes are also examined in the same manner. It is found that the Chinese code for design of masonry structures(GB50003—2001) of proposed models is most suitable and foreign existing models give highly uncertain values of the compressive strength, whereas foreign code values are uncertain as well as perhaps over-conservative. Incorporation of a model uncertainty factor is also achieved.
