摘　　要：通过对HRBF500级细晶钢筋混凝土短柱在水平反复荷载作用下的抗震试验研究,分析了剪跨比、轴压比和配箍率对HRBF500级细晶钢筋混凝土短柱破坏形态、滞回特性的影响,并将试验得到的承载力与采用现行《混凝土结构设计规范》(GB 50010—2010)公式计算结果进行了比较。研究结果表明:试验柱承载力随混凝土强度的增大而增大;试验柱在水平反复荷载作用下发生的都是脆性的剪切破坏,延性差;采用现行《混凝土结构设计规范》(GB 50010—2010)公式计算HRBF500级细晶钢筋混凝土短柱的受剪承载力过于保守。Based on seismic experimental study of HRBF500 reinforced concrete short columns under cyclic lateral loading, the influence of shear-span ratio, axial compression ratio and reinforcement ratio on the failure mode and the hysteretic characteristic was analyzed. The bearing capacity obtained by the test was compared with the results computed by formula from Code for design of concrete structures（ GB 50010--2010）. It shows that the bearing capacity of experimental columns is increased with the increase of concrete strength, the failure characteristic of experimental columns is brittle shear failure, and ductility of experimental columns is very bad. The shear capacity of short columns given by Code for design of concrete structures（GB 50010--2010） is very conservative.
