Modelling of viscoelastic concrete behavior with respect to recent observations in macroscopic tests

Research output: Chapter in Book/Report/Conference proceedingConference contribution

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.
