对我国、美国、欧洲和加拿大混凝土规范中钢筋混凝土构件受剪承载力的可靠度进行对比分析。分析中作用、材料强度和几何尺寸采用相关研究报告或相关文献提供的概率分布和统计参数,受剪承载力计算模式不定性统计参数采用国内外415个无腹筋和178个有腹筋钢筋混凝土构件受剪承载力的试验结果与计算结果的分析值。结果表明,对于无腹筋和有腹筋构件,我国规范受剪承载力的可靠指标均大于加拿大规范,小于美国和欧洲规范,其中,对于无腹筋构件,欧洲规范最大,对于有腹筋构件,美国规范最大。除集中荷载作用下我国、美国、欧洲和加拿大的无腹筋构件和均布荷载作用下我国的无腹筋构件受剪承载力的可靠指标不能满足目标可靠指标要求外,其他基本上能满足要求。
The comparative analysis of the reliability of shear strength of reinforced concrete members in China, the United States, Europe and Canada. Analysis of the role of material strength and geometry using the relevant research reports or related documents provided by the probability distribution and statistical parameters, shear bearing capacity calculation mode uncertainty Statistics using 415 non-web bars and 178 web-reinforced concrete components by Test results of shear capacity and analysis results of calculation results. The results show that for the non-web and web-like members, the reliable indexes for the standard shear strength of our country are all larger than the Canadian standard and smaller than those of the United States and Europe. Among them, the European standard is the largest for the non-web members and the largest for the web members . In addition to the concentrated load of China, the United States, Europe and Canada without web members and uniform load under the load-bearing capacity of non-web members of China’s reliable index can not meet the target reliability index requirements, the other basically to meet the requirements.
