Estudio Patológico al Punto Fijo (Escalera) del Bloque 12 de la Ciudadela "La Esperanza" del Municipio de Aguazul, Casanare

Abstract

The objective of this study was to carry out a pathological analysis of the fixed point (staircase) of block 12 in the “La Esperanza” residential complex, located in the municipality of Aguazul, Casanare. This structure corresponds to the access stairs that connect four levels and allow the entrance to sixteen residential units. It was built in the early 2000s under the regulations in force at that time: the Colombian Seismic Resistant Construction Regulation (NSR-98). The methodology was structured in three phases. The first consisted of a reconnaissance of the structure by means of a documentary review and visual inspection, identifying characteristics such as a system of moment-resistant metal frames, as well as visible damage such as corrosion and rust. The second phase corresponded to the diagnosis of the pathologies previously identified, through the application of non-destructive tests (penetrating liquids and inspection with Scan C), focused mainly on the columns of the second and third floors, due to their greater degree of affectation. The third phase included the formulation of recommendations for the corrective intervention of the detected damage. The results showed that the most recurrent pathology is corrosion in the lower part of the columns, especially in the area of contact with the floor slabs. A significant loss of material thickness was detected, going from 6.70 mm to a minimum of 2.65 mm, which represents a reduction of 60.44 %. This condition requires a technical intervention in the short or medium term, according to the current state of the structure.
