An earthquake of 2015 caused serious damage on historical monuments in Nepal. The monuments are mostly composed of brick masonry and timber. The purpose of this study was to understand the mechanical properties of bricks, mud mortar, and masonry constituting historical buildings of Nepal. Results showed that the average compressive strength and Young’s modulus of unit bricks, mud mortar, and masonry prisms were 5.05 N/mm^2, 1.40 N/mm^2, and 1.70 N/mm^2, and 4.30 x 10^3 N/mm^2, 1.17x 10^3 N/mm^2, and 3.10 x 10^2 N/mm^2, respectively. The Poisson’s ratio for unit bricks and mud mortar were 0.238 and 0.147, respectively. Similarly, the average value of shear strength and shear deformation angle of masonry wall were 0.054 N/mm^2 and, 4.46x10^-2 rad., respectively. We concluded that the results of this study will be a good reference for detailed analysis of historical brick masonry buildings of Nepal in static and dynamic loading. |
