Background: Topology and shape of the structures are very important in terms of the building’s weight and cost. Regarding structural performance, dual structural systems, consisting of steel moment resisting frames with chevron braces, have many applications worldwide and especially in Iran. Methods/Statistical analysis: In this paper, construction cost optimization of dual structural systems is investigated for the different number of floors, span lengths, and soil types. In total, 18 building models are examined and estimated for costs, which are defined in accordance to the architectural requirements for parking areas and code regulations for design. Storey heights are assumed to be 3.5 meters for all models and the construction site is in Tehran, Iran with very high earthquake risks. Construction cost is estimated based on the current Iranian price list. Findings: The obtained results are compared to each other, regardless of the land price and then the optimal ratio between the land price and construction costs is calculated for the most favorable model. The findings show that 5-storey structures with shorter span lengths (5.6 meters) are more economical. However, in the case of 10 and 14-storey structural models, 7.5 meters span for parking of three vehicles, is more economical. In the other words, by increasing the height of the building the optimum span length increases. In addition, the type of soil has a remarkable effect in the total structural cost by increasing the height of the structure Application/Improvements: The results of this article are very useful for engineers to decide how to locate columns and frame elements in a specific plan in order to achieve an optimal layout.
