Today's challenges comprise climate change, urbanization, and demographic change. The building industry is of major technical and economic importance for these subjects. Due to the versatility, structural concrete is the major applied material in building industry. The associated cement production contributes significantly to the CO2 emissions. Hence, new technologies and planning methods as well as production and recycling techniques have to be developed to account for a fast changing world and to reduce the carbon footprint. High-performance materials, such as textile reinforced concrete, in combination with new construction methods and conceptual designs, can reduce the material usage significantly. In this paper, new construction methods as well as conceptual designs are proposed, which result in economic structural members.
