Optimal Cost Basis for Seismic Design

Document Type: Proceeding Paper

Part of: Dynamic Analysis and Design Considerations for High-Level Nuclear Waste Repositories


The paper summarizes a methodology for establishing seismic design levels based on a cost-benefit assessment. The methodology requires the development of costs and benefits for varying design levels of vibratory ground motion and surface fault displacements. The optimum design level for a given structure is that which gives the minimum total direct and earthquake consequence costs. The example used is the surface facilities of the proposed high-level waste repository at Yucca Mountain, Nevada.
