Evaluación de vulnerabilidad sísmica y diagnóstico de patología estructural en el municipio de Villavicencio, caso de estudio: Edificio La Voz del Llano

Abstract

In this project, it intends to evaluate the structural integrity of the La Voz de Llano Building, mainly identifying its characteristics and background. For this, a methodology is proposed that identifies step by step the causes of the problem that exists in the building, in terms of structural pathologies and seismic vulnerability. Initially, a structural survey is carried out accompanied by a visual inspection that includes photographic registration, allowing a thorough characterization of the structural and architectural elements, consequently laboratory tests such as Ferro Scan, Extraction of concrete cores, Depth of carbonation and sclerometry, which recognizes the mechanical properties of the materials and their state of vulnerability, in addition to this, the results of the laboratories gives us certainty of the critical points of the structure speeding up the diagnosis of existing pathologies, as well contributing to the opinion of the causes and consequences of structural effects, which subsequently allows us to give recommendations for improvement.

However, with the data obtained previously, a numerical model is made in a finite element software (ETABS) that represents the behavior of the building and allows us to find the calculation of the overexertion and flexibility indices, contributing to the vulnerability analysis seismic, which was executed with a threshold damage earthquake because the structure is already built and it must only be demonstrated that it will be able to withstand future earthquakes, in the same way this analysis allowed us to identify the elements with the greatest need for reinforcement to guarantee its integrity in a possible seismic event.

The fact of carrying out the seismic evaluation of the building allowed us to know under what solicitations the building is in relation to the resistant earthquake norm (NSR-10), a point that allows to evaluate a structure that was built before said norm, also to know if it meets the necessary requirements to be considered a resistant earthquake building.
