Fibra de carbono en la rehabilitación de columnas y vigas de hormigón armado para aumento de resistencia del antiguo edificio Banco de desarrollo del Ecuador (BIDE), ubicado en la ciudad de Guayaquil.

Abstract

This project focuses on the structural rehabilitation of a frame composed of reinforced concrete columns and beams in the Banco de Desarrollo del Ecuador building, located in Guayaquil. Its main objective is to enhance load capacity and ensure structural stability through the use of carbon fiber-reinforced polymers (CFRP). This intervention addresses the deterioration caused by factors such as carbonation and deficiencies in the original design, providing a technical solution aligned with current international standards. Visual inspections, destructive, and non-destructive tests (such as sclerometry, pachometry, and core extraction) were conducted. The collected data were integrated into a computational model using ETABS software. A structural reinforcement was then designed following NEC-2015 and ACI 440.2R-17 standards, utilizing Sika CarboDur® software to size and simulate the CFRP application in critical elements. The proposal included a detailed cost analysis and technical specifications for implementing the reinforcement. The results demonstrated a significant improvement in the structural capacity of the reinforced elements, enhancing their resistance and reducing seismic vulnerabilities. CFRP proved to be an effective, sustainable, and viable solution, ensuring the building's prolonged service life. The project concludes that CFRP rehabilitation ensures the functionality and safety of the structure, recommending its application in similar buildings located in seismic zones.
