Abstract :In this paper, an algorithm is presented for the optimum design of geometrically non-linear steel space frames using tabu search. The design algorithm obtains minimum weight frames by selecting suitable sections from a standard set of steel sections such as American Institute of Steel Construction insert ignore into journalissuearticles values(AISC); wide-flange insert ignore into journalissuearticles values(W); shapes. Strength constraints of American Institute of Steel Construction—Load and Resistance Factor Design insert ignore into journalissuearticles values(AISCLRFD); specification, maximum drift insert ignore into journalissuearticles values(lateral displacement);, interstorey drift and size constraints for columns were imposed on frames. The performance of the tabu search was compared with simulated annealing and genetic algorithms for two steel space frames taken from the literature. The comparisons showed that the tabu search algorithm resulted in lighter frames
