通过试验，研究了采用在圆孔周边设置加强钢环的腹部开设圆孔的钢筋混凝土梁的破坏特点、加强环筋的应变特点、挠度、裂缝宽度及承载力等力学特性，指出该形式的加强筋对改善开孔梁的受力性能效果不大，远不如孔洞周边配置加强箍筋和斜筋对腹部开设圆孔的钢筋混凝土梁的力学性能影响明显.

The behavior of the reinforced concrete beam with the circularopening is affected by the enhancing stirrups and diagonal reinforcement. This paper, based on the experiment, studies the mechanical behavior of the reinforced concrete beams with the circular opening, which are enhanced by the steel ring. The experimental results are discussed, such as the crack propagation and failure process, the strain of steel ring, the deformation, the width of diagonal cracking, and the capacity bearing shear which shows that the enhancing steel ring can not improve the mechanical behavior of the reinforced concrete beams with circular opening.
