Abstract:     
 
Basierend auf den Forderungen nach schlanken Konstruktionen und einer Optimierung des Bauablaufs, gewinnt die Slim-Floor-Bauweise zunehmend an Bedeutung. Die Bemessung solcher Bauteile kann jedoch nicht allein auf Grundlage der Europäischen Regelwerke für den Verbundbau erfolgen. Es gelten einige Besonderheiten, die durch ergänzende Bemessungsregeln zu erfassen sind. An dieser Stelle wird die Aufmerksamkeit auf die Bemessung im Bauzustand, die Querschnittsklassifizierung und die Biegebemessung gelenkt. Neben den klassischen Querschnitten, bestehend aus gewalzten Profilen mit untergeschweißter Gurtplatte, werden dabei auch in die Decke integrierte hohlkastenartige Profilformen untersucht.

Determination of moment resistance for composite shallow-floor beams - Additional design rules for slim-floor beams.
Due to the demand for sustainable buildings and slim constructions, composite slim-floor systems become more important. The present European Codes do not include complete design rules for shallow-floor beams. In the design, additional regulations have to be considered for ultimate limit state, serviceability limit state and fire design. In this paper the characteristics in erection state, for the cross section classification, the plastic moment resistance and the influence of transverse bending moments are presented. Apart from traditional sections consisting of rolled profiles also floor slabs with integrated steel box-sections have been considered.
