konstantlast

Konstantlast is a term used in engineering, particularly in German-language technical literature, to denote a load that remains constant over time. It describes forces that do not vary during the service life of a structure or machine, in contrast with dynamic or time-varying loads such as traffic, wind, or moving machinery.

In structural engineering, konstantlast is often treated as the permanent or dead load. It includes the self-weight of structural elements (beams, columns, slabs), fixed equipment, attachments, and any other weight that cannot be redistributed or removed during operation. Although called constant, real-world values may change only gradually due to settlement, creep, or retrofits, but they are typically considered time-invariant for design purposes.

Calculation and design use: konstantlast is combined with other loads according to relevant design standards to form load cases and combinations. Designers assess resulting stresses, deflections, and stability under these static actions. In mechanical contexts, konstantlast may describe a constant axial force, thrust, or pressure applied by a stationary component, influencing mounting, foundations, and interfaces.

Applications: the concept is relevant in building design, equipment installation, and machinery foundations where long-term, non-changing forces are dominant. It helps engineers model long-term effects such as settlement and to ensure safety margins and serviceability over the structure’s life.

Limitations: relying solely on konstantlast omits variability and environmental actions. For robust design, it is coupled with variable loads, sealing actions, and potential interactions to account for worst-case scenarios and long-term performance.
