Tragteile

Tragteile is a term used in German-language engineering to denote a structural or machine element that carries loads. As a general concept, Tragteile are components designed to transmit forces, transforming loads into other members or supports. They may be part of civil structures or mechanical assemblies.

In civil and architectural engineering, Tragteile include beams (Träger), columns (Stützen), slabs, walls, and frames that transfer loads from floors, roofs, or equipment to foundations. Materials include steel, reinforced concrete, timber, and composites. The design considers load types (dead, live, wind, seismic) and the geometry to ensure safety.

In mechanical engineering, Tragteile refer to the load-bearing parts of a machine or vehicle, such as the frame, chassis, base plates, supports, and brackets. These components must resist bending, torsion, and dynamic loads, often with connections that transfer forces via bolts, welds, or pins.

Design and standards: Calculation follows structural analysis and codes (e.g., Eurocodes, DIN EN standards in German-speaking regions). Engineers specify cross-sections, materials, and connections, and apply safety factors and serviceability criteria. Joint design and fatigue considerations are critical for bolted or welded connections.

Manufacture and maintenance: Tragteile are manufactured by cutting, welding, machining; inspection includes nondestructive testing, corrosion protection, retrofits for aging structures.
