摘　　要：为研究型钢混凝土柱在压剪工况下各部分轴力分配比例随位移角的发展情况，利用已完成的21个比例为1∶2的型钢混凝土（SRC）柱试件的低周往复加载试验数据，计算得到试件中型钢、混凝土及纵筋承担的轴力随位移角变化的规律。研究表明：随位移角的增大，型钢承担的轴力先减小后增大，在大位移角下型钢承担的轴力可占总轴力的20％～40％。Twenty-one 1∶2 scale steel reinforced concrete （SRC）columns were tested under cyclic loading to investigate the component of axial force at different story-drift angles.The axial forces carried by the shaped steel,the concrete,and the reinforcement were calculated separately based on the test results.It is indicated that：the axial force carried by the shaped steel decreases initially and then increases with the increase of story-drift angle.The proportion of the axial force carried by the shaped steel is 20%-40% of the total axial force.
