Abstract: Composite girders with reduced height and slim-floor girders are an attractive and economical alternative to normal reinforced concrete beams and slabs. Due to the shallow height of these section types their structural behaviour differs decisively from normal composite beams. As a consequence the common design philosophy for normal composite beams leads to uneconomical safe side assumptions for the ultimate carrying capacity and to far too large calculated deformation values for the serviceability limit state. The results of investigations on a slim-floor hat section are presented and some specific problems of these composite section types are discussed. The design method of common composite beams have to be modified for composite girders with reduced height and especially the contribution of the concrete section to the structural behaviour of composite girders with reduced height is relevant.
