The structural system consists of heavy steel braced frame system that supports the main screening mechanisms of the dried process of a copper mine located in a very high seismic area. The building structure has been defined to the local code requirements following conventional analyses and design methods. The new procedure instead is based on a model including the nonlinearities of the structural system and its interaction with non-structural components. The model was run with a series of ground motion records that matches the basic seismic hazard defined by the local code. Results were compared to several performance objectives recommended here for mine facility buildings. The comparison showed that a code-based approach cannot reach a multi performance objective approach leading to an overdesign building. The amplitude of input motions was then systematically increased in order to find an equivalent demand that could potentially reach the performance objectives set in this document. The closest demand to reach a uniform collapse prevention limit was equivalent to a 5000-yr earthquake instead of the 475-yr earthquake adopted originally for design. However, a set of uniform demands that reaches multiple objectives could not be found from the several analyses performed in this study.
