摘　　要：提出了带暗柱Ｔ形柱，进行了４根较小剪跨比（λ＝２．３７５）的Ｔ形柱抗震性能试验，分析了轴压比对承载力、刚度、延性的影响以及设暗柱对提高Ｔ形柱抗震能力的作用。最后进行了理论计算，计算值与实测值符合较好。The T-shaped column with concealed column is presented. Based on the tests of seismic behavior of 4 T-shaped columns with small shear span ratio(λ=2.375), the influence ofaxial pressure ratio on bearing capactity, rigidity, ductility and the function of setting up concealed column in raising seismic capacity of T-shaped column are analysed. And finally,theoretical calculation is completed. The calculating results agree with the measuring ones.
