Title: Time-dependent mechanical behavior of lime-mortar masonry

Abstract:An extensive experimental program has been set up to characterize the time-dependent deformation behavior of masonry, subjected to the creep failure mode. Different types of short-term creep tests were performed on small masonry specimens, which were constructed with air-hardening lime mortar. To assess the influence of the carbonation process on creep behavior, several specimens were subjected to accelerated carbonation. The time-dependent deformations are modeled using a viscoelastic, rheological model which includes damage effects. The applicability of the model is validated by comparing theoretical and experimental results and extending the time frame to long-term predictions. Good agreement was found between experimental and simulated time-dependent deformations. The accuracy of the proposed model is estimated by including the scatter on the most important material parameters in the analysis.
