In this study, an investigation is conducted on how optimally large span steel roof systems are designed in Turkish engineering practice. For this purpose, the optimum sizing of the steel roofs of three indoor swimming pools constructed in different regions of Turkey was performed using the chaotic capacity controlled search (Chaotic-CCS) method and the obtained optimum designs were compared with the original designs of these systems by design office engineers using conventional design approach. As a result, it was determined that the use of structural optimization methods in the design phase of large span steel roof systems will reduce structural weight about 10-40% and thus the cost of structures compared to the original designs. Reducing the use of steel in large span roof systems will not only reduce material costs, but also transportation and construction costs. It will also contribute to sustainability by reducing the impact of the steel industry on the environment.
