“Strengthening Of Masonry Walls With GFRP Straps – Testing and Application”

This paper describes the results of testing of unstrengthened and strengthened masonry walls subjected to horizontal in-plane load. Three kinds of specimens were tested: unstrengthened walls, walls strengthened with horizontal and walls strengthened with diagonal glass fiber straps. For unstrengthened walls and those strengthened with horizontal straps, a numerical simulation was performed. Software called MASA was used for this analysis. This software uses three dimensional non-linear numerical analysis of structure, made of quasi- brittle material, which is described with a microplane model. The results of numerical analysis very well described the behavior of unstrengthened and strengthened walls. In this paper, the application of such kind of strengthening, on rehabilitation of the existing masonry structure, Villa Kallina, in Zagreb, Croatia, was presented.
