摘要
通过对现有试验结果的系统统计分析,研究了钢纤维类型和钢纤维含量特征值对钢筋钢纤维混凝土板抗冲切承载力的影响规律,分析了钢纤维对混凝土抗拉强度的增强效应与钢纤维对钢筋混凝土板抗冲切承载力的增强效应之间的相关关系。提出了钢筋钢纤维混凝土板抗冲切承载力计算建议,供修订我国的《纤维混凝土结构技术规程》及工程设计与施工参考。
Based on the statistical analysis of test results, it is studied that the effects of the types and the characteristic value of steel fiber on the punching shear resistance of steel fiber reinforced concrete plates. The identity between the steel fiber enhancing the tensile strength of concrete and the steel fiber enhancing the punching shear resistance of reinforced concrete plates is analyzed. Propositions are provided for calculating the punching shear resistance of steel fiber reinforced concrete plates. It can be used as a research basis for revising the new Technical Specification for Fiber Reinforced Concrete Structures.
