Abstract
Harmony searchbased algorithm is developed to determine the minimum cost design of steel frames with semirigid connections and column bases under displacement strength and size constraints Harmony search HS is recently developed metaheuristic search algorithm which is based on the analogy between the performance process of natural music and searching for solutions of optimum design problems The geometric nonlinearity of the frame members the semirigid behaviour of the beamtocolumn connections and column bases are taken into account in the design algorithm The results obtained by semirigid connection and column base modelling are also compared to one developed by rigid connection modelling The efficiency of HS algorithm in comparison with genetic algorithms GAs is verified with three benchmark examples The results indicate that HS could obtain lighter frames and less cost values than those developed using GAs
