ABSTRACT / САЖЕТАК:

In the paper part of the analytical, laboratory and quasi-static experimental investigations of designed models of RC columns confined with CFRP will be presented. Particular attention will be paid to behavior of these columns under cyclic loads, whereat a number of comparative analyses of a number of parameters obtained from the experimental investigations of the tested models will be carried out. Some recommendations and outcomes will be given as to the approach and technology of practical application of these materials in Repared and Strengthening of RC Buildings structures, particularly in seismically active regions.
