Hybrid-reinforced rafts for multi-storey buildings

In the course of the compaction of the city centre and the problematic parking space situation, new multi-storey buildings are increasingly being built with underground garages even on several levels. Such foundation slabs are heavily reinforced because of the high loads of the structure, but in addition, a lot of reinforcement is required and governing due to the crack width design. Next to the extensive construction site logistics for such a high amount of reinforcement, high concentration of reinforcement can cause errors during the installation process. By using steel fibre reinforced concrete in accordance with the DAfStb Guideline Steel Fibre Reinforced Concrete, the effect of the steel fibres can be used for both: ULS-design and SLS-design.
