Modern building industry puts large demands on designers. Generally, both the freedom in design as well as the constant pressure on cost reduction exert a strong influence on the design process. For decades many near optimal solutions have been developed for a wide spectrum of engineering problems. However, these standard solutions are based on a standard building architecture that in many cases prevents implementation of these solutions. Today, a structure with complex geometry, load and boundary conditions can be analyzed using widely available software solutions. Despite the ease of designing structures that fulfill requirements for both ultimate limit state (ULS) and serviceability limit state (SLS), the question of an optimal solution is still open. In this paper two optimization approaches, the genetic algorithm and the Hooke-Jeeves method with their hybrid form, are applied for optimization of steel structures with complex constraints (based on PN-90/B-03200 standard): an example of I - beam section shape forming and designing of three-bay frame profiles. The entire analysis together with the optimization process has been developed in the SOLDIS [10] environment.
