Comparison of existing long term deformations with models

摘要

For the description of the long term behavior several different rheological models have been developed, considering normal creep as well as mechano-sorptive creep. However for the application the question arises which model should be used, since especially differences in a prediction of the creep strain after more than 20 years appear. Since tests can hardly be performed over such a long period, the deflection of beams in existing buildings is compared to the values given in the standards as well as to the rheological models.
