Masonry arch was one of the oldest man-made construction techniques that were in existence. This study deals with the behaviour of masonry arch strengthened with steel reinforced grout (SRG) constituted of steel mesh embedded in a cement matrix that was bonded at either extrados or at the intrados portion of the arch. In this study efficiency of strengthening system in enhancing the performance of masonry arches was investigated. Results in terms of load bearing capacity, structural behaviour and failure mechanism were observed from the experimental investigation. The first stage of investigation involved in characterization of materials that constitute the masonry and the strengthening system by mechanical testing. In the second stage, nine arches were tested by means of load control up to the point of collapse. Experimental results of masonry arches strengthened using steel mesh with spandrel fill form the basis for numerical investigation. The results showed that an arch reinforced with steel mesh placed at extrados was more effective in strength enhancement.
