Abstract: Un-Reinforced Masonry (URM) construction is the most common type of construction in rural as well as urban areas due to its lower cost and ease of construction.However, these are weak in resisting lateral loads. The main objective of this study was to investigate the effectiveness of vertical containment reinforcement in mitigating seismic vulnerability of URM buildings using finite element method. URM building of dimensions 6×3×3m with openings in the buildings have been considered.All the walls were assumed to be fixed at their bases along their length. 12mm diameter steel bars were used as vertical containment reinforcement and it was laid on the surface of the walls on both the faces at a spacing of 1m. In this study, time history analysis of the building was carried out forBhuj ground motion. The responses such as base shear and storey deflection of URM buildings were evaluated. The study was concluded that on providing the vertical containment reinforcement along with roof slab and lintel band, the deflection gets reduced by 96 % from that of the building without roof slab, lintel band and reinforcement.
