Verwendung von stahlfaserverstärktem Stahlbeton bei Bodenplatten für automatisierte Hochregallager.

Use of steel fibre reinforced concrete in floor slab for automated high‐bay warehouses In automated high‐bay warehouses, very strict requirements are placed on the deformation of the floor slab, which lead to largely jointless constructions. Steel fibres can be used here on the basis of the DAfStb guideline "Steel fibre concrete" for the verification of the necessary crack width limitation. Furthermore, there are usually very high loads on the floor slab from the racking supports, and in the case of clad rack construction loads from the roof structure must also be taken into account. The inclusion of steel fibres in the punching shear check can help to reduce the slab thickness, as far as the deformation requirements allow, or to do without costly punching shear reinforcement. By means of a practical example, it is shown that a combination of steel fibres and conventional reinforcing steel can be economical. Furthermore, it is explained by way of example which details must be taken into account in terms of execution. [ABSTRACT FROM AUTHOR]
