Estudio Patológico de una Edificación en Guadua, de Cinco Niveles en Betania, Antioquia

Abstract

A five-level patient is presented, built in guadua of the angustifolia Kunth variety, located in the southwest of the Department of Antioquia, in the municipality of Betania. The main objective of this study is to identify, analyze, and evaluate the pathologies that affect the stability and useful life of the structure, taking into account the seismic vulnerability to which it is exposed according to its geographical position. For the development of the diagnosis, a schedule of periodic visits to the project was established, identifying the lesions through a series of visual inspections, field information collection, photographic documentation, and simple manual evaluations to diagnose damage, causes, and symptoms associated with the pathological process. As a result of the diagnosis, three main lesions were identified, distributed in various locations within the structure. These are localized damages, affecting less than 5% of the structural element. The first is crack, greater than 2 mm; the second is a problem of culm rot due to high humidity content (>15%), concentrated in some support of the buildings, which exceed the maximum percentage of humidity allowed, referenced in that, the resistance to tension parallel to the fiber is seriously affected when percentages are below or above 10% and 21%. And thirdly, we found an attack by xylophages in two structural elements (beams), <2% of the cross section of the beams that make up the structure. Finally, the conditions for intervention of the patient are determined, through the removal and partial replacement of the affected elements, in an efficient and economical way, without compromising the structural condition of the building.
