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。
A T-shaped column with a dark column was proposed. The seismic behavior of four T-shaped columns with a small shear-to-span ratio (λ=2.375) was studied. The effect of axial compression ratio on the bearing capacity, stiffness and ductility was analyzed. The role of columns in improving the seismic capability of T-shaped columns. Finally, theoretical calculations are performed, and the calculated values are in good agreement with the measured values.
