ABSTRACT
This paper presents finite
element results of ceramic masonry prisms and walls under concentric
compression. Four different hole geometries of ceramic units were studied
(called Types A, B, C and D). The A-type unit had two rectangular hollows, B-type
and C-type units have two rounded hollows and different net areas, and the
D-type unit had two rectangular hollows and a double central web. This study
analyzed units, prisms and structural walls joined by bedding mortar. The
objective was to verify the stress distribution in units and mortars. The
results showed that the distribution of compressive stress along the length and
width of those units was uniform, but lateral tensile stress along the length
was distinct for different geometries. In addition, this study observed that
hollow shapes have an important influence in stress distribution. The D-type
unit was the one that showed more uniform tension distribution, without peaks
of stress concentration. This indicates that a D-type unit is the most
efficient unit for use in masonry structures.
