Abstract: in this paper the approximate analytical method is applied to structural optimizations for the first time. Adopting an approximate problem of the separable variables' programming to approach the primal problem of structural optimizations, we establish ordinary differential equations describing the curve of ascending the dual objective function. Based on the second order Taylor's expansion, the approximate curve of dual variables is obtained analyticallyt in which the one dimensional search is performed. Num...
