Estudio de patología geriátrica y propuesta de intervención del módulo 4 del nuevo mercado público de Lorica – Córdoba

Abstract

This document shows the general and detailed results of the study of geriatric pathology, seismic vulnerability and design of treatment and intervention alternatives recommended for module 4 of the new public market of Lorica - Córdoba, whose level of constructive progress corresponds to the structure and currently it is in a state of abandonment. It was diagnosed that the damage level of the building due to typical reinforced concrete injuries such as humidity, erosion, fissures, cavities, anthills, detachments and delaminations, among others, amounts to approximately 75%. In addition, it presents an advance of the carbonation front that reached the reinforcement in its majority and a corrosion process with a level of section loss of 15%, for which, under the terms of NTC 5551 - "Durability", it is finished the useful life of the project and started the phase of propagation of the damage or residual life. The primary causes of the injuries and pathologies are based on the intrinsic defects of the structure caused during the construction process and the deficient or null maintenance that has had since its construction. These injuries triggered side effects such as carbonation, corrosion and new injuries associated with this phenomenon. On the other hand, the vulnerability study indicated that the building does not comply with the requirements of flexibility (drifts) and resistance required by the NSR-10. The first viable alternative to treat the building is the integral intervention of all the injuries and pathologies, as well as its structural reinforcement, whose cost amounts to COP $ 542,824,400 ($ 452,353 / m2). The second alternative corresponds to the total demolition and reconstruction and the required amount is COP $ 456,220,594 ($ 380,184.00 / m2), which is why it is considered that the alternative that represents a better cost / benefit and technical favorability corresponds to the latter.
