Sažetak
The paper describes an experimental analysis of masonry columns confined with GFRP straps that were tested under vertical compressive load. The main goal of these experiments was to determine the efficiency of the load bearing capacity of confined columns in relation to the number of confinement layers and the efficiency of spiral in relation to the conventional confinement (fabric is wrapped horizontally around masonry columns). Vertical compression test was made on 3 unconfined and 23 confined specimens. The test results showed that all the confined specimens have a greater load bearing capacity and ductility than the unconfined specimens. The spiral confinement was considerably easier to apply and it would be more acceptable in practical use. These experiments were analyzed using software called MASA. Three-dimensional nonlinear structural FEM analysis was made using microplane model to describe quasi-brittle material. The FEM results showed good compliance with the test results and confirmed that the reason for specimen failure wasn’t the failure of confinement, but a local damage of column specimens.
