Abstract: 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.
Keywords: cold-formed thin-walled C steel;short column; experiment research;finite element analysis; ultimate bearing capacity
