steel arch bridge
Definition
Noun: A bridge whose main supporting structure is an arch made of steel. This type of bridge uses a curved, rigid steel framework to span an opening and support loads by resolving forces into compressive stresses within the arch shape, transferring them to abutments at each end.
Usage
This term specifically refers to the bridge's structural type and primary construction material. It is used in engineering, architecture, and general descriptions of infrastructure. - The city's iconic steel arch bridge has stood for over a century. - Engineers chose a steel arch bridge design for its strength and aesthetic appeal.
Advanced Usage
- As a structural classification: The term is often used in technical contexts to categorize bridge types by their load-bearing mechanics (arch) and material (steel), distinguishing it from, for example, a concrete beam bridge or a suspension bridge.
- In historical context: Many famous landmarks, such as the Sydney Harbour Bridge, are described as steel arch bridges, highlighting their engineering heritage.
