Despite a vast amount of available research on structural optimization, numerical applications addressing real-world structures are very scarce in the literature. Not only does the actual design process in practice have increased complexity and versatility, but also the structures must usually be designed under a high number of load combinations, resulting in prolonged computation times. In this study, the real-world steel structures built in various regions of T & uuml;rkiye have been optimally redesigned for the minimum weight, and the optimum designs of these structures are compared with their original design-office solutions. A recently developed design-driven optimization technique, called the capacity controlled search algorithm, is employed to deliver the cost-efficient designs of these structures in a timely manner. The present study helps fill the gap in the literature regarding the implementation of optimization techniques in industrial applications while investigating how much cost-savings can actually be achieved through structural optimization compared to the original design-office solutions. The results indicate that about 3%-40% cost reduction is possible through the replacement of conventional trial-and-error based design methodology by an optimum design approach.
