Experimental Investigations of Masonry Columns Strengthened by SGFRP under Eccentric Loads

Abstract:

5 masonry columns were strengthened by Sprayed Glass Fiber Reinforced Polymer (SGFRP) in this paper, and a research of the seismic behavior of them tested by eccentric loading experiment was presented. The failure modes of the strengthened masonry columns were illustrated and strengthening effects of them were discussed. The results showed that the bearing capacity of the reinforced columns increased greatly, and the ductility of them also improved significantly. Comparing the strengthening effects of the columns when the thickness of SGFRP and the number of glass fiber are different, some reasonable reinforce suggestions are proposed.
