Sažetak
The paper describes the experimental research of masonry columns behavior under the load of vertical compression. A total of thirty-four specimens were tested: three unconfined specimens and thirty-one specimens confined with GFRP straps. In addition to the load-bearing efficiency analysis of confined columns in relation to the number of the confinement layers, the intention of these tests was to determine the efficiency of spiral confinement in relation to conventional confinement. The impact of the existing compressive stress in a column during confinement to the final increased load-bearing capacity of the confined column was also studied.. The test results have shown that all of the confined specimens have a greater load-bearing capacity and ductility than the unconfined specimens. The results of spiral confinement were almost identical to the results of conventional confinement, which is vital considering that spiral confinement is easier to perform. The results of the test lead to the conclusion that the presence of compressive stress in a column during confinement does not significantly reduce confinement efficiency. This makes it possible to effectively increase the bearing capacity of masonry columns without the need to previously unload the structure, while the structure is in service. The paper also provides expressions for the estimated increase in the compressive strength of confined columns that well correspond to the testing results.
