Análisis de vulnerabilidad sísmica y valoración de patólogias estructurales, caso de estudio: edificio balcones de la 30. Villavicencio, Meta.

Abstract

This document presents the results obtained from the evaluation of the structural conditions of the Balcones De La 30 building, with the purpose of preserving its operation during a seismic event. This was carried out under the procedures established in Chapter A-10 of the Colombian Seismic Resistant Construction Standard (NSR 10), where the condition of the structure is established through the evaluation of its seismic behavior. For this purpose, a methodology was established to identify, through a systematic process, the causes of the building's problems based mainly on seismic vulnerability and structural pathologies. Initially, an architectural survey was carried out together with a visual inspection of the structural pathologies presented in the building with their respective photographic record, which allowed a detailed characterization of the structural elements, then laboratory tests were carried out such as the extraction of concrete cores and the sclerometry test, in order to know the mechanical properties and the state in which these materials are found, likewise, the results obtained through these tests contributed to make a diagnosis of the structural affectations found in the building. Finally, a numerical model was made using finite element software (ETABS), which represents the behavior of the structure under serviceability limit conditions, contributes to the seismic vulnerability analysis of the structure and allows identifying the elements that are in poor condition and need a prompt intervention.
