摘　　要：自密实混凝土工程应用逐渐增多,为研究钢筋自密实混凝土梁的受剪性能,进行了4根钢筋自密实混凝土梁试件和2根普通钢筋混凝土梁试件的试验,研究自密实混凝土梁受剪性能的破坏形态、开裂荷载、裂缝发展和抗剪承载力,并且将其与普通钢筋混凝土梁作对比分析。将试验值与GB 50010—2010《混凝土结构设计规范》计算的理论值与相比较。结果表明,竖向集中荷载作用下,钢筋自密实混凝土梁与普通钢筋混凝土梁有着相似的破坏特征与承载能力。钢筋自密实混凝土梁理论值与试验值的比为0.59,比普通钢筋混凝土梁理论试验值的比值高出0.11。The engineering application of self-compacting concrete （SCC） is increasing. For studying the shear capac- ity of reinforced SCC beams, four SCC beams and two corresponding normal concrete beams were tested. Meanwhile the failure forms, cracking loads, crack developments and shear strengths of the SCC beam are studied by comparing with those of the normal concrete beam. In addition, the experiment results are also compared with theoretical value of GB 50010--2010 ＂Concrete Structure Design Code＂. The results show that failure characteristics and capacity of the two kinds of beanas are almost the same. The capacity ratio of experiment result to theoretical value of the SCC beam is 0.59, which has an increase of 0. 11 than that of the normal beams.
