摘　　要：型钢混凝土柱在长期荷载作用下混凝土承担的轴力将向型钢部分转移，在考虑混凝土徐变对轴力分配影响的基础上，提出了一种新的轴向力分配方法，该方法与试验结果吻合较好。With the axial force is loaded over a long period of time, it will be transferred from concrete to steel shape in steel reinforced concrete columns. Based on the fact that axial force distributing in concrete or steel shape is affected by concrete creep, this paper present a method for axial force distributing. The calculating results with the proposed method correlate well with the test results.

关 键 词：型钢混凝土柱 轴力分配 长期荷载 徐变
