Seismic Performance of Concrete Buildings in Chile

Abstract eng:
Chile is characterized as the country with the largest seismicity in the world. This produces strong earthquakes every 83±9 years in the Central part of the country, where 60% of the population lives and those of Magnitude 8 or higher occur every 10 years. The short interval between large earthquakes of magnitude 8.0 or larger (3 in the last 5 years) has shown that the Chilean seismic design practice has achieved almost "operational" performance level, despite the fact that the Chilean Code uses “life safety” performance level. This article presents a review of the current Chilean practice for the seismic design of concrete buildings based on the displacement demand records of the last three major earthquakes: Maule 2010 (Mw=8.8), Iquique 2014 (Mw=8.2) and Illapel 2015 (Mw=8.4). Conclusions are drawn for the definition and calibration of the Earthquake Design Levels and the Performance Levels for the new Chilean Code of Performance Based Seismic Design under development.
