| 摘 要： | 通过对收集到的集中荷载作用下无腹筋简支梁试验数据的分析,研究了集中荷载作用下钢筋混凝土无腹筋简支梁受剪性能的主要影响因素及其规律.在此基础上,通过对比分析研究,定量评价了我国混凝土结构设计规范公式、美国ACI规范公式、以及其它两种无腹筋梁受剪承载力公式对无腹筋梁抗剪内在机制反映的准确性.

| Abstract: | On the basis of available testing data of simply supported reinforced concrete beams without web reinforcement under two-point concentrated loads,the dominant factors contributing to shear performance are identified,and the basic laws are correspondingly quantitatively described.The shear design equations of China Design Code of Reinforced Concrete Structures,ACI Code,together with two other expressions of shear of RC beams without web reinforcement,are thus calibrated to identify their accuracy in describing the shear mechanism of such members. |

| Keywords: | reinforced concrete beam shear longitudinal reinforcement ratio shear-span ratio |
