In an initial evaluation of possible reinforcement solutions that fulfil the TailorCrete requirements as regards automation and complex shapes, traditional reinforcement and steel fibres were chosen as the most promising alternatives. Textile reinforcement can be of interest when a thin structure is needed. To design the reinforcement for concrete structures with complex shapes, a rational method is needed. Two available methods, based on linear finite element analyses using shell elements, were evaluated, and one of them was chosen to be the better one. Furthermore, cross-sectional models, e.g. such as given in the FIB Model Code 2010, are needed in design. Comparing these suggestions with experiments of beams and slabs including both ordinary and steel fibre reinforcement; it was shown that the capacity was underestimated in design. Nonlinear finite element analyses were used to develop and verify a more advanced modelling method; these analyses showed a better agreement to experiments. Experiments on two-way slabs also provided improved knowledge on effect of fibres on the load distribution and the ability to redistribute. One essential factor that needs to be fulfilled to be able to include the structural effects of the fibres is to be able to verify the quantity and distribution of the fibres. A prototype of a device for a quality monitoring system for verification of fibre amount and type in the fresh concrete was built and evaluated during field tests, and it was proved that the inductive measurement principles work.
