摘要

摘要: 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。

Abstract: Reliability analyses are made for shear capacity of RC members designed by GB 500102002, ACI 31808, EN 1992-1-1: 2004 and CSA A23.32004. In the analyses, load, material strength and geometrical parameter are described by probability model and statistical parameters provided by relevant study reports and literatures. Model uncertainty of calculation formulae of shear capacity is determined based on the experimental results of shear capacity of 415 reinforced concrete members without stirrups and 178 members with stirrups at home and abroad. It is concluded that reliability index of shear of reinforced concrete members without or with stirrups designed according to the code in China is larger than that in Canada, but smaller than that in America which is largest for members with stirrups and Europe which is largest for members without stirrups. Most members basically meet the requirements of target reliability index, except for reinforced concrete members without stirrups under point loads based on Chinese, American, European and Canadian code and members with stirrups based on Chinese code.
