钢筋混凝土界面抗剪承载力可靠度对比分析
|
摘要
对中国规范、美国规范及欧洲规范中钢筋混凝土构件界面抗剪承载力的可靠度进行了对比分析。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,抗剪承载力计算模式不定性统计参数采用国内外127个钢筋混凝土构件抗剪承载力的试验结果与计算结果的分析值。结果表明:规范GB 50010—2002界面抗剪承载力的计算可靠指标最小,未能达到目标可靠指标要求;其余规范公式的计算可靠指标均能满足目标可靠指标要求,其中JGJ 1—91与EN 1992—1—1:2004公式的计算可靠指标较大,偏于保守;ACI 318—08的可靠指标介于中间并与目标可靠指标接近。
Reliability are analyzed and compared on the shear resistance of the interface of RC members as given in GB 50010—2002,JGJ 1—91,ACI 318—08,and EN 1992—1—1:2004.The probability distributions and statistical parameters for loads,strengths of materials,and geometrical parameters are taken from the relevant reports and literatures.The statistical parameters for model uncertainty of calculation formulas of interface shear resistance are taken from experimental results of 127 RC interface specimens at home and abroad.Results indicate that the calculated reliability index based on GB 50010—2002 is the smallest and is less than the target reliability index.The calculated values of the remaining codes can meet the requirements of target reliability indices well.The calculated reliability indices according to JGJ 1—91 and EN 1992—1—1:2004 are larger and relatively more conservative,while that according to ACI 318—08 is moderate in value and is closer to the target reliability index.
