Automated limit state design of steel structures
A comprehensive computer-based method is presented for the optimum design of large prismatic box-girder structures, using a limit state approach. The method contains three principal features: (i) a rapid, design-oriented finite element program developed especially for structural optimization; (ii) a comprehensive set of subroutines for the accurate estimation of the various modes of ultimate strength and other limit responses, most of which are highly non-linear; (iii) an optimization method based on a new from of sequential linearization which is capable of solving the resulting large-scale, non-linear, highly constrained optimization problem. The objective may be any continuous non-linear function of the design variables, such as weight or cost.
