Estudio comparativo entre un pórtico de un vano de acuerdo a la Norma Ecuatoriana de la Construcción (NEC) con un pórtico construido de manera informal

Abstract

Most of the buildings in Ecuador are informal constructions, which means they are at risk because they are constructed on the basis of experience of the failure of some of these buildings. The reasons for this problem are the optimization of costs and time but without considering safety. Both the urban and rural sectors are made up of informal constructions; that is to say without any knowledge of the behavior of structures in front of a risk, such as an earthquake; they only have knowledge from what they have learned because of the failure of other structures. In this project a description is made of the construction of two full-scale models, built in different ways, of an empty structure of one span, to the height of one story with the purpose of comparing their structural behavior under the same load, since the purpose was to represent a real construction as close as possible. The first model was built following the ECUADORIAN STANDARD OF CONSTRUCTION (NEC-SE) to compare it to the second model, which was built by a bricklayer and his assistant, who contributed with their experience to building it without having a proper knowledge of the behavior of a structure.
