| description | The main aim of the current paper is to optimize the seismic design of steel moment-resisting frames, with a focus on minimizing life-cycle costs. An efficient and powerful Physics-based metaheuristic algorithm, known as the center of mass optimization, is utilized to search the design space of steel moment-resisting frames' performance-based design optimization problem. Four seismic design optimization scenarios are examined, considering initial cost and seismic total cost as the objective functions to be minimized, with plastic hinge rotation constraints and inter-story drift constraints as the local and global indicators of structural nonlinear behavior, respectively. Within the context of this paper, seismic total cost is formulated as the simple sum of the initial cost and seismic life-cycle cost of the structures. Two design examples, comprising 6-story and 12-story steel frames, are illustrated. The obtained numerical results indicate that optimizing seismic total cost with constraints on both plastic hinge rotation and inter-story drift yields the most cost-effective designs. Additionally, the findings indicate that in optimization processes including both kinds of design constraints, the inter-story drift constraints dominate the optimal designs. |
