The main goal of this research is to create an advanced framework for evaluating the performance of architectural structures. Structures have various functions beyond just providing support, stability, and cost-efficiency. This study suggests using state-of-the-art numerical analysis to assess the quality of structures in architecture. It focuses on evaluating the qualitative performance of space frame structures in Tehran, using five prominent case studies. The assessment encompasses mechanical performance, environmental performance, aesthetics and meaning performance, spatial considerations, and economic factors, utilizing a multi-criteria decision-making method. In this research, the Delphi method is used to determine the primary criteria. Then, the Analytic Hierarchy Process (AHP) is employed to assign weights to each criterion and rate each case study accordingly. The scores are then used to rank the case studies. The analysis showed that Milad Tower received the highest overall score, followed by Imam Khomeini International Airport. The Tehran International Exhibition Center and Tehran Book Garden also demonstrated strong performances in specific areas. However, Azadi Stadium had the lowest overall score. Milad Tower showed the most balanced performance across various criteria. These results emphasize the importance of considering multiple factors when evaluating architectural structures.
