Abstract: (4028 Views)
The primary objective of this paper is to assess the seismic life-cycle cost of optimally designed steel moment frames. The methodology of this paper involves two main steps. In the first step, we optimize the initial cost of steel moment frames within the performance-based design framework, utilizing nonlinear static pushover analysis. In the second step, we perform a life cycle-cost analysis of the optimized steel moment frames using nonlinear response history analysis with a suite of earthquake records. We consider content losses due to floor acceleration and inter-story drift for the life cycle cost analysis. The numerical results highlight the critical role of integrating life-cycle cost analysis into the seismic optimization process to design steel moment frames with optimal seismic life-cycle costs.
