Abstract
A numerical and analytical model for prediction of serviceability limit states of flexural
reinforced concrete members is outlined. The considered beam elements are investigated
under short-term and long-term bending load. The numerical and analytical model is
validated using existing experimental data. Both analyses provide reliable estimation of
in-service deflections. A multi-directional fixed crack model is included in the numerical
model to account for the non-linear post-cracking behaviour of concrete. For long-term
analysis, time-dependent effects of concrete, creep and shrinkage are employed in both
models through viscoelastic concrete behaviour.
