Estudio patológico a las oficinas administrativas del Colegio Departamental la Esperanza Villavicencio-Meta

Abstract

In this document the results of the pathological study are shown to the administrative offices of the academic coordination of the La Esperanza Villavicencio-Meta Departmental College, through the clinical history, diagnosis and possible intervention alternatives following the current norms, generating a balance between cost -Benefit to the user, has a structure that are more than 25 years old and is currently working. The structural element object of this study is the gutter channel of the offices, the level of damage of the structural element was identified, identifying injuries such as humidity, erosion, dirt by superficial deposition, corrosion by oxidation, vegetal biochemical process and the detachment of the concrete. In addition, according to the results of the phenolphthalein test, it is found that the concrete is carbonated. From the exploration of races, the reinforcing steel is found to be in a state of corrosion, so it could not be identified if the steels are corrugated or smooth, and finally with the Colombian Technical Standard NTC 3692 Test method to measure the rebound of hardened concrete where it is obtained that the estimated strength of the channel beam is less than 1500 PSI (10.34 MPa), and taking into account the building regulations earthquake resistant NSR 10 in the title A that contemplates the minimum requirements for the design and construction of buildings; due to the fact that initial designs are not available to give a diagnosis of minimum compliance with building design requirements, which did not allow a full evaluation of the vulnerability analysis. The first proposal of intervention corresponds to the demolition of the channel beam, which must be constructed and designed to guarantee the collection of rainwater from the two decks. The second proposal is the dismantling of the structure of the roof in order to carry out a general roofing and demolition of the existing beam, stopping the injuries found in the analysis of the pathological study. Solution No. 01 is considered as the best intervention proposal, since it provides benefit-cost, whose intervention has less intervention time.
