Abstract: This contribution presents a comparative study of different modelling assumptions for the
effect of viscoelasticity on the stress development in hardening and restrained concrete. The
goal was to analyze the performance of an alternate model developed by [1] and [2], which was
developed with regard to the insights gained with measurements in several on-site monitorings
in mass concrete as well as with restraining frame experiments.
The results of the presented comparative study indicate, that the experimentally observed
effects of viscoelastic behaviour in hardening concrete cannot be consistently reproduced with
the application of basic assumptions in today’s creep modelling, namely similarity of creep in
tension and creep in compression as well as consequent application of superposition.
