Abstract
On April 22, 1991, an earthquake of magnitude 7.7Mw generated a great amount of damage in the structures located in the Caribbean zone of Costa Rica. The follow-up of the earthquake-resistant design code available at that time (Costa Rican Seismic Code 1986), as well as the recommendations given in the current regulations (Costa Rican Seismic Code 2010/14), are used to assess the observed damage in some structures, to identify if they were caused by a breach of the regulations of that date or due to lack of development in the regulations. In this document, three structural typologies are evaluated through representative cases: reinforced concrete buildings, concrete masonry structures, and elevated structures to be flood resistant. For this evaluation, a photographic record available in the Earthquake Engineering Laboratory was analyzed. All photographs were taken by members of the Laboratory during inspection campaigns carried out days after the main event.
