Design of low-weight steel frames using ant colony optimization
Abstract
A design procedure utilizing an ant colony optimization (ACO) technique is developed for discrete optimization of steel frames. The objective function considered is the total weight (or cost) of the structure subjected to serviceability and strength requirements as specified by the American Institute for Steel Construction Load and Resistance Factor Design (AISC-LRFD). The design of steel frames is mapped into a modified traveling salesman problem (TSP) where the configuration of the TSP network reflects the structural topology, and the resulting length of the TSP tour corresponds to the weight of the frame. The resulting system is minimized using an ACO algorithm with a penalty function to enforce strength and serviceability constraints.
