Abstract

The objective of this study is to investigate the effectiveness of an alternative technique for strengthening masonry columns, based on the use of steel cords. Although fiber-reinforced polymer (FRP) strips or jackets are successfully used as strengthening elements for this kind of application, such a strengthening method represents a new opportunity to restore ambit, with considerable development in unreinforced masonry wrapping. Thus, to assess the potential of steel cord wrapping, this paper presents the results of an experimental program consisting of 48 solid-brick specimens subjected to uniaxial compression load. Different cross-section geometry (octagonal, square, and rectangular) and different amounts and different schemes for confining reinforcement were investigated. The primary experimental outcomes are presented and discussed in the paper considering the mechanical behavior of specimens and the axial stress–axial strain relationships. Test results have shown that the investigated confining systems are able to provide significant gains, both in the compressive strength and in the deformation capacity of masonry columns.
