Análisis del refuerzo longitudinal y transversal en vigas y columnas de hormigón armado utilizando acero de refuerzo con dos fluencias, mediante ensayos de carga

Abstract

In this project a comparative analysis of prefabricated and traditional elements considered as prefabricated elements that have a yield stress of 5000 kg / cm2 and there are assembled in factories and as elements traditions that have a yield stress of 4200 kg/cm2 and its armed in construction. The analysis was performed has as purpose view load bearing capacity of the elements are beams or columns when these acts on a point force in the case of flexure and shear generates beams, and columns generates compression. After testing we had the capabilities of the elements and these results proceeded to make comparisons between prefabricated and traditional elements as load bearing capacity and ductility of the element. In addition, we performed several modeling of each element in different computations programs in order to get another point of comparison. Finally a redesign of the prefabricated elements because there do not meet the requirements demanded by the codes for earthquake-resistant systems is proposed.
