摘　　要：进行钢纤维自密实混凝土构件设计时通常需要用到抗压强度指标,但是目前预测钢纤维自密实混凝土抗压强度的公式很少。定义了钢纤维有效增强因子,并对试验数据回归分析,提出一个预测钢纤维自密实混凝土28 d抗压强度的模型。使用模型计算了文献中钢纤维自密实混凝土的抗压强度,并与实测数据比对,结果表明预测强度与实测强度符合的很好。In the process of the Steel Fiber Reinforced Self-Compacting Concrete （SFRSCC） component design,the compressive strength fre- quently be used.However,the compressive strength prediction model of SFRSCC is less.The conception of effective fiber reinforced factor was de- fined.The regression analysis on experiment data was presented.On these bases,the prediction model for 28 d compressive strength of SFRSCC was put forward.It was used to calculate the compressive strength of SFRSCC in a journal article.The predictions were compared with test values, it shows that the calculations show good agreement with the experimental results.
