[提要]  通过11根混凝土强度等级为C14的简支梁试件在集中荷载作用下的试验研究，得到外粘整块钢板后梁的受剪承载力。随粘钢规格的不同，粘钢混凝土梁发生不同的破坏形态。根据试验结果，建立了粘钢部分承担的受剪承载力理论计算公式和受剪斜截面限制条件。

Based on the experimental study of eleven simple-supported RC beams with externally bonded steel plates under the concentrated load,the shear load capacity with concrete strength grade C14 is obtained. The failure circumstances of the beams with externally bonded steel plates are varied with their dimension. According to the test results,the computational formula of the shear load capacity about the externally bonded steel plates and the restricted condition of oblique shear section are set up.
