摘　　要：以单筋矩形截面受弯构件的正截面承载力计算为例,介绍了钢纤维混凝土受弯构件的截面设计方法;通过与普通混凝土构件进行比较,证明混凝土中掺加钢纤维,可显著提高钢筋钢纤维混凝土梁的正截面承载力.Taking calculation of normal section bearing capacity of single-side reinforced rectangular flexural member as an example,the application of steel fiber reinforced concrete flexural member sectional design method of was introduced.Based on the comparison with ordinary concrete member,it is proved that steel fiber mixed in reinforced concrete can significantly increase normal section bearing capacity of reinforced concrete beam.

关 键 词：钢纤维 受弯承载力 计算公式
