Fast Seismic Life Cycle Cost Optimization of Steel Moment Frames to Improve Seismic Performance
Abstract This study presents a fast method of Life Cycle Cost (LCC) optimization of structures. One of the main obstacles to implementation of seismic lice cycle cost optimization is the time-consuming process of evaluating the possibility of failure of the structure. To overcome this restriction, in the proposed approach, the probability of failure is estimated using fragility functions. A fast method for developing the fragility function was employed in this paper to reduce the computation time. Two well-studied frames, adopted from the literature, were studied to demonstrate the implementation of the methodology. A comparison of results with previous studies indicates that a reasonable increase in the initial cost substantially reduces damage and life-cycle costs of the structure. It also significantly improves the seismic performance of structures. The proposed method can be employed to design more reliable and economical structures.
