Steel composite constructions, such as steel beams with cast-in-place concrete, are typically modeled by representing beam and surface elements with different properties. In conjunction with the construction stages, the creep redistributions that occur could also be easily calculated. The creep coefficients ψ_L, which depend on the type of loading, take into account the different stress ratios in the cross-sectional elements.

In this way, any composite structure could be realistically calculated.
