Resumen
La existencia de una gran cantidad de edificios antiguos ha movilizado la investigación para estudiar nuevos sistemas de refuerzo a aquellas construcciones que sean dañadas por decadencia fisiológica o por terremoto. El presente documento demuestra la eficacia de un sistema de refuerzo innovador para los muros de mampostería, constituyentes los elementos estructurales de los edificios históricos. Se hace una comparación entre unas redes bidireccionales de fibras sintéticas tradicionales y las de fibras naturales, ambas pegadas a las dos fachadas del muro con matriz de mortero. El resultado muestra la aplicación de las fibras de cáñamo como refuerzo sísmico y una mayor compatibilidad de estas con el material que caracterizan los edificios antiguos.
Abstract
The existence of a large number of old buildings has mobilized research to study new systems of reinforcement to those buildings that are damaged by physiological decay or earthquake. This document demonstrates the effectiveness of an innovative reinforcement system for masonry walls, which are the structural elements of historic buildings. A comparison is made between bidirectional networks of traditional synthetic fibers and those of natural fibers, both glued to the two facades of the wall with mortar matrix. The result shows the application of hemp fibers as seismic reinforcement and a greater compatibility of these with the material that characterize the old buildings.
