摘　　要：为了研究自密实混凝土梁正截面受弯性能,设计了5根自密实混凝土梁,2根普通混凝土梁。对试验梁的开裂荷载、极限荷载、截面不同高度处的平均应变、刚度和裂缝进行了研究,并且在普通混凝土梁相关计算公式的的基础上,给出了自密实混凝土梁的刚度、裂缝、界限受压区高度计算公式和正截面承载力计算方法.Five self-compacting concrete beams and two corresponding normal concrete beams were designed to study the hearing properties of flexural members of self-compacting concrete, and their cracking loads, utmost loads, average strain in different heights of section, rigidness, and crack were investigated by experiment. And on the basis of methods to calcuate common concrete members, the formulas to calculate the rigidity, crack and ultimate height of compression strain of SCC as well as the method to calculate the bearing capacity were provided.
