belastningsforhold

Belastningsforhold is a term used in engineering to describe the set of loads and environmental factors acting on a structure or component during its service life. It encompasses the magnitude, direction, distribution and time variation of forces that must be considered in design, assessment and verification of safety, functionality and durability.

The concept covers several categories of loads. Permanent or dead loads arise from the structure itself, including self-weight of beams, slabs and fixed installations. Variable or live loads come from occupancy, furnishings, movable equipment and other changing use. Environmental loads include wind, snow, rain, temperature changes and other weather effects. Dynamic and impact loads account for vibrations, machinery, traffic and accidental events. In seismic regions, earthquake loads are considered as well. In practice, combinations of these Belastningsforhold are analyzed to capture worst-case stresses and deformations.

Design and analysis often rely on load cases or load combinations specified by codes and standards. Engineers evaluate the structure under different belastningsforhold to ensure adequate strength, stability and serviceability. This may involve static and dynamic analyses, as well as time-dependent effects such as creep, shrinkage or fatigue under repetitive loading.

The exact meaning and treatment of belastningsforhold vary by country, language and code. While the general idea is universal in structural engineering, the specific rules for combining loads, partial safety factors and acceptance criteria differ between jurisdictions and standards such as Eurocodes or national building codes.
