Intermittloads

Intermittloads are a concept primarily found in the field of civil engineering, specifically related to the analysis and design of structures subjected to varying loads. These are loads that are not applied continuously over the entire lifespan of a structure. Instead, they are present intermittently, meaning they are applied and removed periodically, or they may vary significantly in magnitude over time. Examples of intermittloads include the weight of vehicles on a bridge, the impact of waves on a coastal defense structure, or the forces generated by machinery within a factory.

The analysis of intermittloads is crucial for ensuring structural integrity and longevity. Unlike static loads that are constant, intermittloads introduce dynamic effects and fatigue considerations. Repeated application and removal of a load, even if below the material's ultimate strength, can cause cumulative damage over time, leading to fatigue failure. Engineers must account for these cyclic stresses in their designs, often employing specialized design codes and calculation methods that consider the frequency, magnitude, and duration of the intermittent loading. The study of intermittloads also involves understanding the statistical distribution of load occurrences and magnitudes to predict the probability of extreme load events. This allows for the design of structures that can safely withstand anticipated intermittent stresses throughout their intended service life.
