Burned clay brick masonry is a commonly used building unit for structures. Improving the earthquake resistance of such structures is vital due to the increase in the occurrence of seismic events globally, affecting larger populations and aging/deterioration of the masonry. Generally, conventional synthetic material-based strengthening techniques are widely used for structures, which is carbon-intensive and not climate-friendly. Therefore, to strengthen brick masonry structures seismically, various techniques for enhancing earthquake resistance using locally available natural fibers are investigated and presented in this study. The use of locally available natural fibers helps in reducing emissions and carbon footprint overall, apart from providing good thermal insulation. In this study, a finite element model of a two-story brick masonry building strengthened with natural fiber-reinforced polymer (FRP) composites subjected to earthquake ground motions is developed. Linear dynamic analysis of the buildings without and with strengthening is performed under uniaxial earthquake ground motion. The dynamic response of the buildings, i.e., peak shear force, acceleration time histories, stress distribution, crack propagation patterns, and overall earthquake resistance of the buildings is compared. An enhancement in the dynamic performance of the building is reported on the adoption of strengthening measures using a variety of natural fiber elements. The flax FRP composite is observed to be the most effective in strengthening the masonry structure under static and seismic load scenarios. The study contributes to proposing sustainable practices in seismic risk mitigation for existing as well as new structures.
