摘　　要：为了研究钢骨混凝土异形柱的受力性能和影响因素,在试验研究的基础上编制了非线性分析程序。对非线性分析得到的承载力与试验进行比较可知,二者误差较小。分析了加载角、偏心距、含钢率、混凝土强度等级以及肢长厚比对构件承载力的影响。结果表明:含钢率的变化对构件的极限承载力影响明显,且极限承载力随着截面含钢率的增大而增大。最后对十字形实腹式钢骨混凝土异形柱实用设计方法进行了探讨。The procedure of nonlinear analysis has been compiled based on experiment for studying the force performance and effect factors of steel reinforced concrete cross-shaped columns.A good agreement was shown between the bearing capacity of nonlinear analysis and experiment.Load angle,eccentric distance,steel ratio,concrete strength grade and length-thickness ratio had been analyzed.The results show that steel ratio affects the bearing capacity,and the bearing capacity can be increased along with the increasing of steel ratio.Finally,the design method of the cross-shaped steel column was discussed.
