This article validates numerically the experimental behavior of a reinforced concrete frame subject to cyclical
loads, resorting to a commercial program using finite element analysis. The experimental results were obtained in the
National Laboratory of Civil Engineering (LNEC). In the numerical simulation several constitutive models were used,
with different degrees of complexity, based on the concept of local plastification in critical zones (plastic hinges) of the
elements that constitute the frame as well as on fiber models.This paper reports research developed on Cyclic Response and is associated with a thematic on Base Isolation under the R&D Eurocores Project COVICOCEPAD within the S3T Program, approved independently by European Science Foundation (ESF, Strasbourg), financially supported by “FCT -Fundação para a Ciência e a Tecnologia” (Lisbon, Portugal) under Programa Operacional Ciência e Inovação 2010 (POCI 2010) of the III Quadro Comunitário de Apoio funded by FEDER
