The present paper describes a numerical model that has been developed in order to analyse the long-term behaviour of beams built in different stages under serviceability loads, considering the effect of delayed deformations due to creep and shrinkage. The rheological model for concrete creep is based on a modified version of the solidification theory while the cross section behaviour is described by means of a fibre model. The paper discusses the performances of the model in simulating the behaviour of two fullscale beams tested by the authors.

Abstract
The present paper describes a numerical model that has been developed in order to analyse the long-term behaviour of beams built in different stages under serviceability loads, considering the effect of delayed deformations due to creep and shrinkage. The rheological model for concrete creep is based on a modified version of the solidification theory while the cross section behaviour is described by means of a fibre model. The paper discusses the performances of the model in simulating the behaviour of two fullscale beams tested by the authors.| File | Dimensione | Formato | |
