This contribution studies a well-known failure criterion and its application\nto the life-time prediction of adhesive anchor systems under sustained load.\nThe Monkman-Grant relation, which has previously been applied to a wide range\nof materials, is now applied to adhesive anchors installed in concrete. It\npostulates a linear relationship between the logarithm of stable creep rate and\ntime to failure. In this paper the criterion is evaluated first on a large\nexperimental campaign on one concrete involving two chemically different\nadhesives and then by several experimental data sets reported in literature. In\nall cases the data is well represented and highly accurate predictions are\nobtained. The second part of the paper focuses on the relationship between\nstable creep rate and relative load level of the remote constant stress based\non the Norton-Bailey and the Prandtl-Garofalo creep laws. The latter was found\nto perform better on fitting the experimental data. Finally, the combination of\nthe Monkman-Grant criterion and the aforementioned creep laws allows the\nprediction of stress versus time to failure curves including uncertainty\nbounds, that are in very good agreement with all experimental data sets, making\nit an interesting alternative to existing test methods for adhesive anchor\nsystems under sustained loads.\n
