Abstract
This paper reports on the findings and observations of the team sent by PCI to investigate damage caused by the February 2010 earthquake in Chile. The paper concentrates on the performance of precast concrete
structures, although some other aspects are also included. The majority of structures performed acceptably or better, considering the severity of the earthquake. Much of this is attributable to Chile’s history of adoption and implementation of adequate building codes. The success of advanced precast concrete structural systems, based on research in the United States, was demonstrated. The Chilean precast concrete industry is mature, sophisticated, and, in the absence of constraints imposed by restrictive building codes, quite innovative. Code implications of lessons from the February 2010 earthquake are also discussed.
