Abstract

 This study focuses on the seismic performance evaluation of unreinforced stone masonry wall
piers in typical residential buildings in Nepal, utilizing the finite element method (FEM). The
seismic coefficient method is employed to calculate the horizontal and vertical loads on the
masonry wall pier. Key findings indicate that the wall piers are more vulnerable to shear
failure and diagonal tension compared to toe crushing and rocking failures. The failure modes
suggest that stone masonry buildings in Nepal typically fail due to shear and tension during
earthquakes. From this analysis the shear stress reached 1.67 N/mm2 at the end of the load
steps. Additionally, a simplified micro-analysis reveals the in-depth behavior and local failure
mechanisms of the masonry under seismic loads.
