SEISMIC PERFORMANCE OF RC BUILDING COLUMNS CONFINED WITH CFRP

Abstract

It is a usual practice that traditional methods with traditional materials (most frequently jacketing of elements) are used for repair and strengthening of structures. However, lately, particularly in the last two decades, there have occurred new construction materials intended for strengthening and design referred to as composites strengthened by polymer fibers (FRP). These materials have special mechanical properties and special properties.

In the paper part of the 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 quasi-static 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, particularly in seismically active regions.
