Earth:Stepped profile
A stepped profile describes the edge of something that has a series of defined steps.[1] It has applications in architecture, construction, engineering, and geology.
Applications
Architecture and construction
In building design a stepped profile is used to reduce the visual impact of, or airborne noise around a building.[2][3][4] A stepped profile is also used to calculate seismic and wind loads in multi-story building design.[5]
The spillway from a dam can have a stepped profile, which dissipates energy from the released water.[6]
Engineering
In engineering, a stepped profile may be used on a bearing surface to reduce friction between the moving parts.[7]
Geology
A mountain with a stepped profile has a number of denudation terraces caused by erosion.[8]
A river with a stepped profile has a step-like variation in its gradient along its length.[9] This may be caused by changes in the height of the underlying bedrock.[10]
Notable examples
- Altar Mountain, a mountain in Victoria Land, Antarctica
- Drapers' Gardens, an office block in the City of London, United Kingdom
- Cairn of Barnenez, a neolithic monument in Brittany, France
