The application of Steel fiber Reinforced Polymer (SRP) as a means of increasing the capacity of masonry columns is investigated in this study. The behavior of 23 solid-brick specimens that are externally wrapped by SRP sheets in low volumetric ratios is presented. The specimens are subjected to axial monotonic load until failure occurs. Two widely used types of masonry columns of differing square cross-sections were tested in compression (square and octagonal cross-sections). It is concluded that SRP-confined masonry behaves very much like Fiber Reinforced Polymers FRP-confined masonry. Confinement increases both the load-carrying capacity and the deformability of masonry almost linearly with the average confining stress. A comparative analysis between experimental and theoretical values computed in compliance with the Italian CNR was also developed.

Abstract
The application of Steel fiber Reinforced Polymer (SRP) as a means of increasing the capacity of masonry columns is investigated in this study. The behavior of 23 solid-brick specimens that are externally wrapped by SRP sheets in low volumetric ratios is presented. The specimens are subjected to axial monotonic load until failure occurs. Two widely used types of masonry columns of differing square cross-sections were tested in compression (square and octagonal cross-sections). It is concluded that SRP-confined masonry behaves very much like Fiber Reinforced Polymers FRP-confined masonry. Confinement increases both the load-carrying capacity and the deformability of masonry almost linearly with the average confining stress. A comparative analysis between experimental and theoretical values computed in compliance with the Italian CNR was also developed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
