Non-Standard Fügeprinzipien für leichte Bauteile aus UHPFRC

Non-standard principles for joining lightweight members made from UHPFRC

Despite the enormous developments in digital design and fabrication methods our thinking in the construction industry is still dominated by the standard of industrial production. The profiles and semi-manufactured parts made from steel and wood as well as the on the market available formwork systems for concrete structures imply the simplest possible geometry and addition. Consequently, today's load-bearing structures are usually composed of bending stress mass-intensive components. Lightweight form-active structures such as built in 1972 Lufthansa Maintenance Hall V at Frankfurt airport, however, are hard to find. In the future, the efficient use of materials and energy will have a crucial importance for the implementation of sustainable construction. Instead of avoiding complexity at the cost of increased masses, the goal for the future will be to save mass by using structural efficiency. The opportunity for this lies in the combination of the latest developments in material technology with the digital planning and production. The aim for high-tech materials such as ultra high performance fibre reinforced concrete (UHPFRC) must be to develop material appropriate non-standard joint principles that are produced economically despite increased complexity. This is where the present contribution starts showing the current research results for innovative principles for joining lightweight members from UHPFRC.
