Abstract
Even when meeting specifications imposed in standards and
building codes, concrete roof tiles are fragile and may be readily
damaged during shipping, laying, and subsequent use. This
paper describes a research project conducted to develop new
mechanical tests for determining roof tile performance with a view
to improving roof safety during and after tiling. Three flexural
and two nibs test methods and four tile types were studied. One
of the new tests designed improves on the standard methods by
reducing variability—among other factors—and yields results
consistent with the failure patterns observed in roofs. An efficient
new method was developed for testing nibs. The highest ultimate
load was reached when the nibs broke simultaneously. The impact
on the findings of tile shape and size, as well as variations in the
manufacturing processes, was suggested; and regression equations
were formulated as a basis for the design and production of
stronger tiles.
