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.
