[en] Dry-stacked masonry walls gives rise to geometric
imperfections: the height variation of different masonry blocks ΔH and
the roughness of the support area Δh. This paper studies the effect of ΔH
on the structural response and the load bearing capacity of masonry walls
by highlighting the load percolation. Furthermore, an algorithm was
developed to define a stress multiplier coefficient respecting the
imperfections ΔH. The algorithm allowed predicting 77% of the amplified
stress compared to the FE analysis and showed that the geometric
imperfections govern the load percolation in a wall as well as the
cracking mode and the bearing capacity.
