Seismic performance evaluation of stone masonry wallet

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