Shear Failure of Historic Masonry Walls

Abstract

Historic masonry walls have showed excessive weeknesses and very low shear capability whenever subjected to seismic loads. The behavior of historic unreinforced masonry (HURM) walls under combined compression and shear loading plays a essential position in the seismic confirmation of masonry structures. Experimental research on historic masonry were taken out by the author on shear walls and triplets developed with total clay bricks in scale 1:3rd to determine the shear behavior of HURM walls. On the foundation of experimental investigation, a shear criterion for HURM has been presumed. It appears that the shear strength of masonry raises with the pre-compression up to a limit and turns into constant at higher pre-compression. Lastly, the experimental load-deflection connection and cracking distribution alongside the surface of the shear walls have been investigated with the hypothetical outcomes attained by a non linear FE analysis of HURM walls and a good co-relation was discovered between them.
