Carbonzugglieder unter statischer und nicht ruhender Beanspruchung – Erste Ergebnisse aus dem Forschungsverbundvorhaben NeZuCa.

Tension member made from carbon fiber polymer composite subject to static and fatigue loads – first results from joint research project NeZuCa For high availability of bridge infrastructure, solutions are needed that can withstand high traffic loads reliably and contribute to climate protection through resource savings. The principle of the network arch bridge allows for efficient and low‐deformation bridge structures with spans of over 300 m, using slender primarily axially loaded main members. The use of high‐performance carbon materials (unidirectional carbon‐fibre‐reinforced polymers, UD‐CFRP) allows for an extremely efficient lightweight solution for highly stressed tension members and offers potential savings in the primary structure. Carbon tension members are currently not regulated by building authorities. For the basis of an individual approval (ZiE), project‐specific component tests financed by the respective client were used for initial applications. Within the framework of the joint research project NeZuCa (Network Arch Bridges with Carbon Tension Members), component tests under static and non‐static loading conditions, as well as additional investigations, are conducted to establish the basis for a standardized and simplified application of the technology. This article presents the initial results reported by the project consortium. NeZuCa is supported by the Federal Ministry for Economic Affairs and Energy as part of the Lightweight Construction Technology Transfer Program (TTP‐LB) and is supervised by the Project Management Agency Jülich (PTJ).
