| 摘 要： | 介绍准确确定钢筋混凝土简支梁的计算跨度(求弯距、剪力),使梁的受力更加合理,用新旧规范对梁的纵向受力钢筋进行配筋计算比较,结果表明按新规范计算梁的配筋及采用新规范混凝土标号对梁的强度有明显加强。

| Abstract: | The article explained how to get the effective span,bending moment and shear of unstable reinforced concrete simply-supported beam in order to make the tension in beam more rational.The steal ratio of forced longitudinal bar of beam was calculated and compared respectively by old and new criterion,the conclusion showed that the strengthen of beam was promoted obviously under the new regulation and by new concrete grade in new criterion. |

| Keywords: | effective span minimal steal ratio longitudinal bar concrete grade |
