Concrete structures are very sensitive to long-term structural performance. This phenomenon has paramount importance for serviceability, durability and long-time reliability of such structures. This is why a reliable prediction of behaviour of structures during their construction as well as during their service life is extremely important. One of the most important factors which provide perfect function of concrete structures (serviceability, loading capacity, durability) is real and correct prediction of creep and shrinkage – i.e. development of long-term deformations. So for its prediction have to be used apposite and calibrated mathematical models - due to this fact Model B3 is very good and efficient for use.

The intention of this Special Session will be theoretical papers and papers describing practical usage of the model B3 for concrete creep and shrinkage prediction.
