چکیده	This study addresses the critical necessity for optimized structural design under fireconditions, where conventional methods often prove inadequate. The research focuses on theoptimal design of two three and nine story steel moment-resisting frames, withoutfireproofing protection. The optimization objectives were to minimize the structural weightwhile satisfying constraints under critical fire scenarios. The key design constraints includedinter-story drift and the demand-to-capacity ratio of structural members. The studyemployed the Enhanced Vibrating Particles System (EVPS) and the Accelerated WaterEvaporation Optimization (AWEO) algorithms. A significant aspect of the investigationinvolved analyzing various severe fire scenarios to identify which parts of the structures aremost vulnerable during a fire event. The results demonstrate the effectiveness of theproposed optimization framework in achieving a lightweight yet resilient structural designthat meets regulations under extreme thermal loading.
