ABSTRACT
Composite beams subjected to static actions exhibit an increase in deflections and deformations over time as well as a redistribution of stresses between steel beam and slab due to cross-section heterogeneity. Considering the applied external actions to remain constant with time, the resultant bending moment does not undergo significant changes over time. Theoretically, these differences become negligible for composite beams with stiff shear connections and where the only stress redistributions taking place are those between the concrete slab and the steel girder, with slab unloading over time and redistributing its stresses to the steel component.
