Evaluación y rehabilitación de elementos estructurales deteriorados vigas y columnas de hormigón armado de un edificio de 3 pisos en Guayaquil

Abstract

CONDITION FOR PUBLICATION OF PROJECT. The evaluation and rehabilitation of deteriorated structural elements is an essential process to ensure the safety and durability of buildings. In this project, a comprehensive structural diagnosis of a three-story building located in Guayaquil was carried out, focusing on the analysis of two columns and a beam. The main objective is to identify the degree of deterioration of these elements, especially due to carbonation and insufficient concrete strength. Based on the initial assessment, it is proposed that the most affected elements present safety risks, which justifies the need for interventions to preserve the structure in the long term. For the development of this project, destructive and non-destructive tests, such as pachometry, sclerometry and coring, were performed to evaluate the strength of the concrete and the depth of carbonation. In addition, structural modeling in ETABS was used to simulate the response of the structure to different loads. Standards such as NCE15 and ACI 318-19 were followed to ensure the reliability of the results. The results obtained indicated that columns B3 and beam C1 PA showed relatively low resistance and advanced carbonation, while columns B4 and C1 PA showed a good structural condition. Interventions such as concrete jacketing and preventive treatments were recommended, together with a periodic monitoring plan, so that the rehabilitation of the deteriorated structural elements would guarantee safety and prolong the useful life of the building. Key words: structural rehabilitation, carbonation, destructive testing, non-destructive testing, structural modeling.
