Field earthquake reconnaissance has revealed that masonry corner
failure is one of the most common failure mechanisms. In literature, few studies
have focused on the experimental investigation of such a mechanism, and they
were usually performed considering the seismic action passing from the corner
bisector. The present study conducts an experimental campaign on masonry
corners and investigates how the orientation of the seismic action affects both
the seismic capacity and the collapse mechanism. The experimental campaign
involves two masonry corner configurations with different wall aspect ratios.
Both configurations are made of a single-leaf dry-joint specimen, built with
calcium silicate blocks. Results demonstrate how the orientation of the
pseudo-static load simulated by means of a tilting table affects the structural
capacity.
