This paper explores the viability of using energy dissipators for implementing earthquake-resistant measures for common vulnerable buildings in Chile. Hysteretic devices (e.g. based on plastification of metals) are considered. This study deals both with design of new buildings and retrofit of existing ones. Three 3, 5 and 10-story RC buildings are analyzed; each building is designed for five situations: no seismicity, rock soil in seismic zone 3 in Chile with full/reduced seismicity, and soft soil in the same zone with full/reduced seismicity. The behavior of these buildings is analyzed in terms of modal parameters and capacity curves (after pushover analyses). The seismicity is characterized in terms of input and hysteretic energy; using this information, the optimal design parameters of the dissipative devices are obtained.
