摘　　要：提出了带暗柱的L形柱，进行了4根较小剪跨比以（λ＝2.375）的L形柱的抗震性能试验，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L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得较好。The L-shaped column with concealed column is presented. Based on the tests of seismic behavior of 4 L-shaped columns of smaller span ratio(A= 2.375), the influence of axial pressure ratio on bearing capactity, rigidity, ductility and the function of setting up concealed column in raising seismic capacity of L-shaped column are analysed. And finally, theoretical calculation is completed. The calculating results agree with the measuring ones.
