摘　　要：基于二次受力迭合梁斜截面受力性能和钢纤维混凝土材料特性 ,分析了钢纤维混凝土迭合梁截面的剪应力分布规律。与钢纤维混凝土整体梁相比 ,钢纤维混凝土迭合梁存在剪应力“超前”现象 ,其超前值随着第二阶段荷载的增大而逐渐减小 ,直至完全消失。Based on the double stress of steel fiber reinforced concrete (SFRC) composite beams and their material performance, a law of shear stress redistribution in SFRC composite beams is studied Compared with SFRC general integral beam, SFRC composite beams have a phenomena of “stress excess of tensile steel” The value of stress excess gradually will be decreased with the loading at the secondary stage until complete vanishing
