摘要
本文通过１６根高强砼柱的试验，研究了高强砼框架柱的抗剪性能，讨论了剪跨比、轴压比等因素对破坏形态、开裂剪力及抗剪强度的影响。对现行规范的抗剪计算公式的适用性进行了探讨。研究成果填补了国内高强砼框架柱抗剪强度研究的空白，可作为编制高强砼设计规范的参考。
On basis of the experiment on sixteen high strength concrete columns, their shear behaviors are analysed. The effects of shear-span ratio and axial compression ratio on failure behavior, cracking shear and shear strength are analysed. The authors have discussed the suitability of the design equations for shear strength in the code. This experimental study on shear strength of high strength concrete frame columns is the first one in this field at home and the results can be served as reference for the code of high strength concrete design.
