Abstract (EN): During last decades, have been made many studies about RC columns under uniaxial and biaxial horizontal cyclic loading, however, the knowledge about biaxial behavior is far of uniaxial behavior knowledge. Due to testing difficulties and because there are still open questions regarding the cyclic behavior both in 2D bending with constant axial force, very few experimental studies have, as yet, tackled the more general problem of 2D bending on repaired and retrofitted columns. In this work is presented the results of an experimental study about behavior under uniaxial and biaxial bending, with constant axial load of as built RC columns. Six columns were tested, three under monotonic loading and three under biaxial cyclic loading with diagonal loading path on as built specimens. After experimental work, was made a numerical nonlinear analysis to evaluate the accuracy of existent models in the representation of the RC columns behavior during a seismic event.
