Considering the variety of urban buildings from the point of view of regularity and irregularity, it is important to examine their life cycle cost (LCC); this issue has not yet been fully explored in previous research. On the one hand, the lack of utilization of building information modeling (BIM) in previous structural design-based LCC research is evident. This research aims to highlight the impact of irregularity on the LCC of structures by providing an integrated framework based on the seismic design optimization of structures by using LCC and BIM capacities. For this, a shared environment is created in MATLAB software, information is exchanged between Revit, Etabs, and Excel software, and optimization is done using NSGA-II for establishing a trade-off between initial cost and LCC. BIM tools can greatly reduce the limitations of LCC analysis, such as information exchange time, and increase the accuracy and speed of calculations. By modeling six models in two regular and irregular types, the framework of the research and the difference in the behavior of the structures are examined. The results showed that the indirect costs of irregular structures are more than the regular ones. In addition, the findings show that reducing the LCC of irregular structures compared to regular ones requires a higher initial cost percentage. For example, for regular and irregular 13-story structures, a 17% increase in the initial cost leads to a 48% and 40% reduction in their LCC, respectively.
