| 摘 要： | 分析了配筋量的多少与能获取的单筋矩形截面梁正截面抗弯承载力大小的规律。认为 ,配筋量与抗弯承载力理论上呈二次抛物线关系 ;但当配筋量变化幅度不大或变化幅度大而相对受压区高度处于较小区间时 ,配筋量与抗弯承载力均呈近似的线性关系。

| Abstract: | The effects of reinforcing bar amount on bending_resistance bearing capacity of normal section in single_side reinforced rectangular beam is analyzed. The analysis results show that the relation in theory between quantity of reinforcement and bending_resistance bearing capacity is about two_times parabola, but it will be linear when the quantity of reinforcement varies within a proper range or the height of relative compression_area is in small size. |

| Keywords: | quantity of reinforcement rectangular section normal section bending-resistance bearing capacity |
