| Abstract: | Double optimal design variables are reduced into a
single optimal design variable, and the optimization design model of
pre-stressed concrete filled square steel tubular column is established
accordingly. By using penalty function method, the iteration formulas of
optimal design variables are derived, and the calculation procedure of the
double iterative method is given in this paper. The numerical example shows
that it is simple in concept and convenient for solving
cross-section optimization design problems of pre-stressed square steel pipe concrete
columns, and it provides a better approach for nonlinear programming. |
