Rahmenträgerkonstruktionen

Rahmenträgerkonstruktionen, often translated as frame structures or portal frames, are a common type of structural system used in building and civil engineering. They consist of interconnected beams and columns that form rigid or semi-rigid frames, designed to resist applied loads through bending, shear, and axial forces. The key characteristic of a rahmenträgerkonstruktion is the moment-resisting connection between the horizontal beam (Riegel) and the vertical columns (Stützen), which allows the frame to act as a single unit. This rigidity enables the frame to support significant loads and span larger distances compared to simple beam-column arrangements.

These structures are particularly prevalent in industrial buildings, warehouses, sports halls, and bridges where wide, open spaces are required. The design of a rahmenträgerkonstruktion involves determining the optimal size and shape of the members, as well as the type of connections, to ensure stability and safety under various load conditions, including dead loads, live loads, wind, and seismic forces. Materials commonly used include steel, reinforced concrete, and timber. The versatility and efficiency of frame structures make them a fundamental element in modern construction, offering flexibility in architectural design and functional utility.
