Eigengewichte

Eigengewichte, a German term often translated as "dead weight" or "own weight," refers to the self-weight of a structural element or system. In engineering and physics, it is a fundamental consideration when calculating the total load a structure must bear. This includes the weight of materials used in construction, such as concrete, steel, wood, and glass, as well as any permanent fixtures attached to the structure.

Understanding eigengewichte is crucial for ensuring structural integrity and safety. Engineers must account for this constant, inherent load to accurately determine the required strength of foundations, beams, columns, and other load-bearing components. It forms the basis for calculating other types of loads, such as live loads (variable loads from occupants or movable objects) and environmental loads (like wind or snow). Ignoring or underestimating eigengewichte can lead to structural failure.

The concept applies across various disciplines. In bridge design, the weight of the bridge deck, girders, and supports contributes significantly to the eigengewichte. For buildings, the mass of walls, floors, and roofs are primary components of eigengewichte. Even in simpler applications, like the weight of a shelf supporting books, the shelf's own weight is its eigengewichte. Accurately calculating and managing eigengewichte is a cornerstone of sound engineering practice, ensuring that structures are designed to safely support themselves and their intended use.
