Abstract
The studies of increase in the bearing capacity of steel-concrete composite girders, as obtained by partial steel section encasement with concrete in the zone of internal bearings, are described. Continuous girders are considered, and composite action is applied to rolled steel girders and reinforced-concrete monolithic slabs of constant thickness. The results obtained show that a significant increase in the bearing capacity of composite girders can thus be achieved, and that this increase is even more pronounced in case of greater spans, and when HE-A steel sections are used.
