An impmved genetic algorithm is presented and applied to the optimization design of steel structures. A software of optimum design toolbox of steel structures is developed, which is based on the improved genetic algorithm and the Code for Design of Steel Structutes (GB50017 -2003). An example demonstrated the convenience and the effectiveness of the optimum desigp software in the optimal desigp of steel structures.
