Abstract
The applicability of the acoustic emission (AE) technique to detect unstable damage accumulation in masonry, subjected to the creep failure mode, is investigated during short- and long-term creep tests on masonry specimens. The damage accumulation is quantified using the results of the monitored AE event rates, which evolve as a bathtub-shaped curve during the last phase of the creep tests. The bathtub curves are described using the Weibull function and a relation is found between the detected AE event rate and the time to failure of the specimens.
