Creep rate based time-to-failure prediction of adhesive anchor systems under sustained load

Original language description

This contribution studies a well-known failure criterion and its application to the life-time prediction of adhesive anchor systems under sustained load. The Monkman-Grant relation, which has been previously applied to a wide range of materials, is for the first time applied to adhesive anchors installed in concrete. It postulates a linear relationship between the logarithms of minimum creep rate and time-to-failure leading to fundamental answers of problems emerging both from research and industry practice. In this paper the criterion is evaluated first on a large experimental campaign on one concrete involving two chemically different adhesives and then by several experimental data sets reported in literature. In all cases the data is well represented and highly accurate predictions are obtained. The second part of the paper focuses on the relationship between minimum creep rate and applied relative load level based on the Norton-Bailey and the Prandtl-Garofalo creep laws. The latter was found to perform better on fitting the experimental data. Finally, the combination of the Monkman-Grant criterion and the aforementioned creep laws allows the prediction of stress versus time-to-failure curves including uncertainty bounds that are in very good agreement with all experimental data sets, making it an interesting alternative to existing test methods for adhesive anchor systems under sustained loads.
