Schubtragfähigkeit und M-V-Interaktion von Flachdecken mit integrierten hohlkastenförmigen Stahlprofilen - Ansatz eines hybriden Fachwerkmodells zur Querkraftbemessung

Shear resistance and M-V-Interaction of Slim-Floor-systems with integrated steel-box sections - Approach of a hybrid truss model for the shear design.

Shallow-floor slabs with integrated steel profiles in composite behavior are mainly characterized by the slim design. Parallel to the traditional sections consisting of rolled profiles with an additional bottom plate also floor-slabs with integrated steel-box sections have gained widespread adoption in practice in the recent years. Because of the sheathing of the concrete by the steel section a hybrid truss model with a compression strut in the concrete section is developed, increasing the shear resistance of these sections. Due to the additional steel stresses resulting by the truss model, the relationship for the interaction between moment and vertical shear forces is to expand.
