Shell structures are known to be extremely high performing and material efficient. There are numerous natural examples. But considerable spans have already been mastered with steel reinforced and prestressed concrete. The idea now to use this positive load-bearing behaviour to be used on a smaller scale as part of large structures. The thesis is that a thin-walled structure-like design of the solid component core, for example in slabs, can achieve a significant weight reduction with the same performance. The preferred material is textile reinforced concrete (TRC), as it can be used to achieve particularly low layer thicknesses of different geometries. In the first part of the CRC/TRR 280 project C01 it is planned to develop an analysis method and software solution appropriate for the design routine of thin-walled structures, first for the general case, later for shell structures inside building components. The second part is the performing of laboratory tests, so that the assumed numerical methods and material models can be checked and calibrated afterwards. The derived results should be used to adjust the controlling points for the uniaxial description of the concrete and reinforcement composite behaviour model as well as used Willam–Warnke failure criterion. Also, the recorded deformation and crack pattern should match the pattern derived in the numerical model. The tests will start with simple geometries. With each test phase, the complexity of the thin-walled elements will be increased. On the basis of initial tests which will be presented in the paper, the basic data transfer routines and usage of the innovative digital fabrication method should be introduced to be used in later stages to reach an appropriate quality and performance in the manufacture processes of geometrically complicated TRC thin-walled structures.
