摘　　要：以钢筋混凝土梁为研究对象,基于平截面假定通过编制非线性计算程序,计算分析了不同配筋率下单筋钢筋混凝土梁和相同受拉钢筋配筋率下,不同数量受压钢筋的钢筋混凝土梁截面的M-φ曲线。讨论了配筋率和受压钢筋配置对钢筋混凝土梁延性及承载力的影响。Reinforced concrete beams are studied,a nonlinear analysis program is built based on plane cross section assumption to analyze singly reinforced beams with different steel ratios and doubly reinforced beams with identical tensile steel ratio and variant compress steel ratios to get their M-φ curves.Finally,the influences of reinforcement ratios and compress steel arrangements on both the ductility and bearing capacity of reinforced concrete beams are discussed.

关 键 词：钢筋混凝土梁 配筋率 M-Φ曲线 延性性能
