Abstract:
This paper presents the results of an experimental program carried out to study the behavior of brick
masonry columns confined by steel reinforced grout (SRG) comprised of continuous steel fiber cords embedded in a
cementitious matrix. Short brick masonry columns with a square cross-section confined by SRG jackets were
subjected to a monotonic concentric compressive load. Parameters investigated in this study were the area weight of
steel fibers and the masonry column corner radius. Results show that the SRG jackets increased the compressive
strength of the masonry columns by 26-42% relative to the unconfined masonry columns. The compressive strength
of the confined columns increased slightly with increasing corner radius ratio and with increasing fiber area weight.
