| 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。 |

| Abstract: | In the process of the Steel Fiber Reinforced Self-Compacting Concrete(SFRSCC) component design,the compressive strength frequently be used.However,the compressive strength prediction model of SFRSCC is less.The conception of effective fiber reinforced factor was defined.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. |
| Keywords: | steel fiber self-compacting concrete effective fiber reinforced factor compressive strength prediction model |
