Análisis comparativo de los costos económicos y de la respuesta sísmica de una edificación considerando dos escenarios: la construcción técnica y la construcción informal, en la ciudad de Ambato

Abstract

Based on the existence of a large number of informally built structures in the city of Ambato, we proceeded to conduct field research to determine the actual background applied during the construction of an informal structure, despite the fact that the owner of the house obtained the permits and plans respectively approved; in addition, a quantitative research method was used by applying the static nonlinear analysis of such structure through a structural calculation software. With the information obtained in situ, the structure was modeled in the calculation software and a static analysis was performed to determine the linear behavior of the structure related to vibration periods, basal shear and floor drifts to compare it with the established in the Ecuadorian construction standard NEC 2015, also, the static nonlinear analysis (PUSHOVER) was applied obtaining the capacity curve and the performance point of the structure. The results of the nonlinear analysis of the structure induce its reinforcement by means of the metal casing technique with angles and plates in the case of the columns and in the case of the beams, the reinforcement is proposed using IPE 160 metal profiles in order to achieve and guarantee compliance with the performance levels expected for this type of structures, in addition this reinforcement significantly increases the cost of its construction.
