摘　　要：本文利用71根约束钢筋混凝土短梁在反复荷载下的试验研究结果，综合分析了剪跨比（跨高比）、梁端上部配筋特征、附加交叉腹筋、垂直与水平分布腹筋、钢纤维、以及剪压比诸参数对短梁的破坏形态、抗弯与抗剪承载力、延性、耗能的影响；同时对提高短梁抗震性能的设计方法进行了研究。最后提出了延性约束钢筋混凝土短梁的抗震设计方法建议。By use of the experimental results of.71 short restrained reinforced concrete beams under re-versed cyclic loading, this paper comprehensively analyzed the effects of such parameters as the shear span ratio (span-depth ratio), characteristics of the top steel, additional cross web rein-forcement, vertical and horizontal web reinforcement, steel fibers and shear compression ratio of the beam ends on the failure modes, bending and shear resisting capacity, as well as ductility and energy dissipating capacity. The design method for increasing aseismic behavior of these short beams has also been studied. Finally, some recommendations on aseismic design of short ductile restrained reinforced concrete beam have been put forward.
