superload
Học thuậtThân thiện
Definition
Noun: 1. A variable, moving load on a structure: A superload is a heavy, often temporary, and dynamic load applied to a structure, such as a bridge or road, typically caused by moving vehicles or equipment that exceed standard design weights. It refers to the specific stress imposed by this exceptional traffic.
Usage
The term is primarily used in civil and structural engineering contexts to describe and plan for extraordinary loads. * Engineers must calculate the bridge's capacity to bear the superload from the convoy of heavy machinery. * A permit is required to transport a superload across state highways. * The design accounts for regular traffic and occasional superloads.
Advanced Usage
- Superload Analysis/Assessment: A specific engineering study to determine a structure's safety and stability under an exceptional moving load.
- The department conducted a superload analysis before approving the transport route.
Variants and Related Words
- Superload Permit (noun phrase): An official authorization required to move an exceptionally heavy or large item on public roads.
- The company obtained a superload permit for the wind turbine blades.
Synonyms
- Exceptional load
- Heavy haul load (more common in transportation logistics)
- Abnormal indivisible load (AIL - a specific technical/legal term in transport)
Notes on Meaning
- Technical Specificity: is a precise technical term. In everyday language, people might describe the same thing as an "oversized load" or "heavy truck," but these lack the specific engineering connotation of a calculated variable force on a structure.
- Contrast with Static Load: It is distinguished from permanent "dead loads" (the weight of the structure itself) and other "live loads" (like stationary crowds). The key characteristic is its movement, which creates dynamic stress.
Noun
- a variable load on a structure (e.g. a bridge) such as moving traffic
