The project focuses on developing modular, resource-efficient, and high-performance construction systems by utilizing thin-walled timber hollow profiles reinforced with high-performance fibers like carbon or glass. These reinforced timber profiles are designed to offer significant improvements in material efficiency, allowing for higher load-bearing capacities with reduced material usage. Unlike traditional solid timber or metal components, the thin-walled profiles optimize the placement of material according to load requirements, resulting in lightweight yet strong structural elements. A key aspect of the project is the development of advanced connection methods that integrate these timber elements into modular structures. These connections, made from fiber-reinforced plastic, aim to eliminate the need for traditional metal fasteners, which are often heavy and susceptible to corrosion and fatigue. The newly designed connections provide superior durability and flexibility, ensuring strong joints between timber components while preserving the lightweight characteristics of the system. This approach allows the construction of stable, modular structures that are both adaptable and sustainable, meeting the requirements of modern, eco-friendly architecture. The integration of these advanced timber profiles and connection techniques facilitates prefabrication, enabling efficient and rapid assembly on construction sites. By reducing the reliance on heavy equipment and minimizing the time required for construction, this system is expected to lower both costs and environmental impact. To demonstrate the technology’s potential, a demonstrator structure will be built, showcasing the effectiveness of these innovative systems in real-world applications.
