| Abstract: | Column with section of concrete-filled square tubes is a new type of special-shaped column and crisscross combined column of concrete-filled square tubes is a representative one. The simplified equation of slenderness ratio is deduced for crisscross combined column of square steel tubes which are connected by the diagonal lacing bar. The feasibility of superposition theory for crisscross combined column of concrete-filled square tubes is studied, and it is verified by the analysis with ANSYS. |
