New construction of a residential area
Location
Merseburger Straße, 07743 Jena

Project descriptionThe foundation slabs of the residential buildings as well as the foundation slab of the underground car park were designed by combining Dramix 5D 65/60BG steel fibre and traditional reinforcement. Due to the WU concept, it was necessary to limit the permissible crack width wk to 0.2mm in the serviceability limit state.
Optimisation with SFRC
- Reduction of reinforcement and elimination of punching strips
- Optimisation of reinforcement details in the planning phase with problem-free implementation on the construction site
- 40 % saving of traditional reinforcement
