000020078 520__ $$2eng$$aIn Chile, earthquake-resistant design of industrial structures and facilities is regulated by Chilean code NCh2369. Even when NCh2369 refers to seismic provisions of AISC as a complementary source of information, both codes present conceptual differences regarding the preferred source of energy dissipation. AISC seismic provisions enforce energy dissipation only through inelastic deformation of specific elements in the structure, which requires a widely distributed inelastic incursion in order to maximize energy dissipation. In an industrial context, providing structural detailing that allows a widely distributed plastification is not simple, given the usual irregularities of mass, stiffness, and geometry that structures exhibit. Considering this, NCh2369 allows dissipation additionally in the structure anchorage to the foundation. The advantage to this approach is that it limits in some way the seismic energy entering the structure, thereby reducing damage during strong earthquakes. In order to study the impact on seismic behavior when either practice is used for design, in this paper two typical structures of mining industry are designed in parallel according to NCh2369 and AISC341 Seismic Provisions requirements. Seismic behavior is characterized through performance factors and methodology as indicated in FEMA P695. Furthermore, seismic energy distribution of the different dissipation mechanisms is studied for each practice. It is observed that utilization of ductile anchorage improves the structural behavior, reducing the seismic demand on resistant elements and increasing the overall ductility.
