The experiments of ultimate bearing capacity on folded line steel box column were also performed, and the proportion of the mode is l:8. Finally, the comparision of the test and the software simulation was carried out. On the basis of them, some suggestions about designing, manufacturing, hoisting and monitoring of folded line steel box column were proposed.
Keywords: folded line steel box column; nonlinear finite element; model experiment; ultimate bearing capacity
