Diseño y rehabilitación en edificación de tres pisos con columnas deterioradas, en coop. Luis Vargas Torres, Guayaquil

Abstract

CONDITION FOR PUBLICATION OF PROJECT. The present project focuses on the rehabilitation of the third floor with deteriorated columns of a building located in the Coop. Luis Vargas Torres, southern Guayaquil. The damage was caused by informal construction, lack of professional supervision, use of inadequate materials, and environmental exposure due to the unfinished structure. These conditions have compromised the durability, stability, and safety of the building, making technical intervention necessary to restore its function and protect its occupants. On-site and laboratory tests were carried out to evaluate the condition of the column materials. As a solution, reinforced concrete jacketing was selected for strengthening, a three-dimensional structural model was developed using ETABS software, where cross-sectional dimensions and reinforcement bars were increased as required. The structural design was verified through drift, flexural-compression, and shear checks in accordance with the Ecuadorian Code NEC 2015 and the international ACI 318-14 standard, achieving optimal performance, confirming that the rehabilitation meets structural and seismic safety criteria. The unit cost per strengthened column was estimated at USD 587,17 offering an economical and sustainable solution compared to demolition and reconstruction, optimizing resources and reducing environmental impact.
