Earthquake Performance
In general, confined masonry buildings performed well in past Peruvian earthquakes (Gallegos, 1994). Poor performance was observed in geographic locations with poor soil conditions.
In the 1970 Chimbote earthquake (magnitude 7.8), extensive damage was recorded when wall-to-floor connection were inadequate (Schultz, 1994). Confined masonry construction was widely used in urban areas located close to the epicenter of the August 2007 Pisco earthquake (magnitude 8.0) (EERI, 2007). In general, confined masonry buildings performed very well in the earthquake. However, confined masonry buildings with irregularities or poor detailing of reinforcement suffered extensive damage.
