Estudio de patología estructural para una edificación de cinco pisos, generada por una explosión, con sistema estructural de muros de carga, localizado en el barrio la Florida de la ciudad de Tunja - Boyacá.

Abstract

It is proposed to reinforce the structure of bulding 8 of the “Multifamiliar Florida Parque” due to an explosion, taking into account the requirements of the Colombian earthquake resistant construction regulation NSR-10. The explosion occurred in apartment 104, due to the illegal manipulation of chemical substances causing, unfortunately, two fatalities and the partial destruction of the apartment and the building, leaving the stability of the structure at high risk. A pathological study is carried out taking into account the stages of clinical history, diagnosis and intervention design including budget. The activities carried out correspond to: for clinical history, information compilation of studies and designs with available architectural and structural plans, photographic record taking and study of lesions. For diagnostic, field tests such as extraction of concrete cores, sclerometries, corrosion potentials, detection of reinforcements, measurement of carbonation of concrete and taking of masonry for compression resistance, geotechnical analysis, verification of the current state of the structure, evaluation of the existing structure and structural seismic vulnerability For the design of the intervention, the requirements of the NSR-10 were updated. The building has a structural system load-bearing walls, masonry walls reinforced with clay bricks vertical drilling, constructed with the duration of the earthquake regulation NSR-98, for intermediate seismic hazard. The evaluation of the structure resulted in non-compliance with the requirements of the earthquake resistant regulation NSR-98, indicating a vulnerable structure, with an index of 0.357. Intervention design proposes the reconstruction of collapsed walls and elements, carrying the structure to its original condition, resulting in compliance with the requirements of regulation Colombian design and construction earthquake resistant NSR-10.
