摘　　要：为研究带垫板的双肢背靠背C型钢轴压短柱的极限承载力,通过试验和有限元分析两种方法对7个该截面类型的短柱进行承载力分析,了解组合柱的破坏形态,得到C型钢型号、垫板厚度和垫板间距等参数对组合短柱的受力性能的影响程度,为该类型构件在实际工程中的应用提供一定的依据。To study the ultimate bearing capacity of axially-loaded double back-to-back C steel short column with gusset plate,seven short columns of this section type were analyzed bearing capacity by experiment and finite element analysis, to understand the destroyed form of the composite columns,and the degree of influence of C steel model,plate thickness and plate spacing on composite columns' loading behavior was got,and provided a basis for the application of this type of structure in practical engineering.
