摘　　要：本文通过对10根承受集中荷载作用下带后浇段的矩形截面钢筋混凝土约束梁的试验结果与已有的普通矩形截面钢筋混凝土约束梁的试验和理论计算结果的对比,发现了带后浇段的约束梁在集中力作用下抗剪强度与普通约束梁的差别,分析了后浇段对抗剪承载力的影响。The test results of ten restrained rectangular beams with post-casting section subject to concentrated loads are presented. The difference of shear strength between the beam with a post-casting section and the common beam is identified through comparison with the known experimental results of common restrained rectangular beams and other numerical results according to Design Code (GBJ10-89) or some theoretical prediction. In addition, the influence of post-casting section on shear strength is studied well.
