| 摘 要： | 同一强度等级的混凝土可能有不同的概率统计参数,对于都服从正态分布、fcu,k相同、σcu不同的两组同一强度等级的混凝土制成的短柱,采用均值一次二阶矩法进行了可靠性计算分析,得出σcu小的可靠度大,σcu大的可靠度小.

| Abstract: | The same strength grade concrete may have different parameters of probability and statistics. The reliability of short columns made by two sets same strength grade concrete which obey normal distribution and have same fcu,k and different σcu was analyzed and caculated by using the mean first-order second moment method. The results indicated that short column with small σcu has high reliability and one with big σcu has low reliability. |
