摘要
根据试验结果 ,分析了钢纤维含量特征值和钢纤维类型等因素对钢筋钢纤维混凝土梁正截面抗裂的影响规律 ,研究了钢纤维对混凝土抗拉强度的增强效应与钢纤维对梁正截面抗裂度的增强效应之间的一致性关系 .
Based on the test results, the effects of characteristic and kinds of steel fiber on cracking strength of normal section of steel fiber reinforced concrete beams are analyzed. The identity between the steel fiber enhancing the tensile strength and the steel fiber enhancing the cracking strength of normal section of reinforced concrete beams is also analyzed. Propositions are provided for calculating the cracking strength of steel fiber reinforced concrete beams.
