As a result of the high demand for dwelling in Latin American countries, the construction of reinforced concrete structural wall systems for high-rise buildings has increased; However, during earthquakes such as Chile (2010) and New Zealand (2011), the seismic performance of this system was not as expected, displaying different aspects of brittle behavior such as out of plane buckling, crushing of the extreme compression zone due to lack of confinement and damage concentration in narrow zones not showing a broad plastic hinge region among other failure modes. Since the typical structural wall thickness used in Colombia is smaller than those used in Chile and New Zealand, it is claimed that the seismic performance of these walls during a strong earthquake will be poor. As a result, research efforts have been intensified through numerical modeling and laboratory tests in order to assess the performance of these walls subject to strong earthquake loading. The present work focuses on the selection, upgrading and validation of a nonlinear model, among the most widely used in recent scientific literature, to represent numerically the behavior of structural walls with characteristic of those usually built in the city of Bucaramanga. The robustness of the model will be compared with models of out of plane inelastic buckling obtained or validated from experimental campaigns available in the scientific literature and relevant parameters in the structural response of this type of walls will be identified.@en
