Abstract
Fiber Reinforced Cementitious Matrix (FRCM) composites can be employed as a valid alternative to Fiber Reinforced Polymer (FRP) composites for strengthening existing reinforced concrete and masonry structures. In this study, the behavior of clay masonry columns confined by steel reinforced grout (SRG) composite with a natural hydraulic lime mortar is investigated. An experimental study was performed to understand the behavior of masonry prisms with varying cross-sections confined by SRG jackets subjected to a monotonic concentric compressive load. Test parameters considered in this study are the density of the steel fibers, column corner radius, number of SRG layers, and the overlap length of the composite. The effectiveness of the confinement is studied in terms of loadbearing capacity, ultimate strain, and energy absorption with respect to unconfined, square cross-sectioned columns.
