Analysis of the stability bearing capacity of biaxial bending cellular steel column with circular hole

In order to promote the application and promotion of the cellular steel columns in practical engineering. Considering the geometric initial defect, geometric nonlinearity, material nonlinearity and residual stress. Using ABAQUS to analyze the effect of parameters of axial pressure, hole spacing, member length, hole size and flange width-thickness ratio on the stability bearing capacity of the cellular steel column, and get the influence of various parameters. The results show that with the increase of the axial pressure, member length and hole size, the stability bearing capacity of the cellular steel column decreases. With the increase of the hole spacing and flange width-thickness ratio, the stability bearing capacity of the cellular steel column increases. It is found that axial pressure, member length and flange width-thickness ratio have a great influence on the stability bearing capacity of cellular steel columns. (paper)
