Abstract
El proyecto refuerzo de estructuras de hormigón armado con materiales CFRP (CarbonFiber Reinforced Polymers), aplicación al caso de refuerzo de una viga típica y a columnasde un edificio de estacionamientos subterráneos, se presenta como procedimiento de diseñoreferencial, para que estudiantes y profesionales, en función de sus necesidades, puedanutilizar y calcular refuerzos estructurales con pletinas o tejidos FRP.Este documento comprende detalladamente los procedimientos que se deben seguir paradiseñar un refuerzo estructural con CFRP ante esfuerzos de flexión, corte, compresión yflexo-compresión en vigas y columnas de hormigón armado; estableciendo también lasventajas y desventajas de esta técnica frente a los métodos tradicionales.Finalmente, en base a los parámetros de diseño presentados, se realiza el reforzamientode una viga a flexión y corte y el reforzamiento a flexo-compresión de una columna. Serealiza una evaluación económica de implementar esta técnica, dando como resultadoimportantes conclusiones acerca del uso del CFRP en el campo de la Ingeniería Civil,relacionados con limpieza en su ejecución y costos.
The retrofitting of reinforced concrete structures with CFRP (Carbon Fiber ReinforcedPolymers), application to the retrofitting case of a typical beam and columns of anunderground parking building, is presented as a referential design procedure, so that studentsand professionals, depending on their needs, can use and calculate structural reinforcementswith FRP strips or fabrics.This document includes in detail the procedures to be followed to design a structuralreinforcement with CFRP in the case of flexural, shear, compression and flexuralcompression forces in reinforced concrete beams and columns; also establishing theadvantages and disadvantages of this technique compared to traditional methods.Finally, based on the presented design parameters, the reinforcement of a beam is flexionand cut and the flexural compression reinforcement of a column is carried out. An economicevaluation is carried out to implement this technique, resulting in important conclusionsabout the use of the CFRP in the field of Civil Engineering, related to cleaning in its executionand costs.
