摘　　要：介绍了钢管混凝土(CFST)和中空夹层钢管混凝土(CFDST)抗剪性能的研究概况。总结了剪跨比、轴压比、空心率、含钢率、混凝土强度、钢管材料、径厚比等不同因素对抗剪性能的影响。结果表明剪跨比、轴压比、含钢率、混凝土强度、钢管材料对钢管混凝土的抗剪承载力有积极的效果,相关结论对中空夹层钢管混凝土的抗剪性能研究提供了进一步的参考。The research situation of shear behavior of CFST and CFDST is introduced.The influence of different factors such as shear-span ratio,axial compression ratio,hollow ratio,steel content ratio,concrete strength,steel tube material and diameter-thickness ratio on the anti-shear performance are summarized.The strength of concrete and steel tube materials have a positive effect on the shear capacity of steel tube concrete.Finally,the relevant conclusions provide further reference for the study of the shear performance of hollow sandwich concrete filled steel tube.
