摘　　要：视混凝土强度参数为随机变量,以Hsich-Ting-Chen强度准则作为混凝土单元失效的极限状态函数,用验算点法计算出单元屈服的可靠指标和相应的失效概率,建立了单元屈服的可靠度判据.通过算例分析了混凝土强度参数均值与变异系数对屈服准则判别结果的影响.结果表明,当变异系数较大时,对单元失效概率的影响显著.Regarding the concrete strength parameter as a random variable and taking the Hsich-Ting-Chen concert strength criterion as the limit state function of concrete element failure,the checking point method was used to calculate the reliability indicators of the element yield and the corresponding failure probability and the reliability criteria of the element yield were established.By means of examples,the influences of the mean of concrete strength parameters and variation coefficients on results determined by the yield criteria were analyzed.The results showed that the impacts on the failure probability of the element were obvious when the variation coefficient was larger.
