Enhancing the Seismic Resistance of Columns by GFRP Confinement Using Flexible Adhesive-Experimental Study

Abstract

In this paper, the results of two experiments, focused on testing the effectiveness of a method of enhancing the seismic (dynamic) resistance of masonry columns with the use of flexible polymer adhesive, are shown. The first experiment was devoted to investigate the damping properties of a polymer working between two stiff layers, whereas the aim of the second one was to verify if the identified damping properties of the polymer can improve the dynamic behaviour of short masonry columns (prisms) strengthened by confinement made of GFRP grid bonded by the polymer adhesive. The results of the first stage of experimental investigation indicate that bonding two stiff elements with the analyzed polymer adhesive leads to the significant increase in overall damping properties. The results of the second experiment show that the GFRP grid confinement with flexible polymer adhesive is more effective than stiff epoxy and mineral adhesives.
