Hyperbolic-paraboloid

Hyperbolic paraboloid geometry as used in saddle roof construction.

A saddle roof is one which follows a convex curve about one axis and a concave curve about the other. The hyperbolic paraboloid form has been used for roofs at various times since it is easily constructed from straight sections of lumber, steel, or other conventional materials.[1] The term is used because the form resembles the shape of a saddle.

Sometimes referred to as a hypar, the saddle roof may also be formed as a tensegrity structure.[2]

Mathematically, a saddle shape contains at least one saddle point.

Imported from Wikipedia

This page is being imported from Wikipedia, to create a Wikidwelling stub or article. These steps need to be completed:

  1. Sections not relevant to Wikidwelling can be deleted, or trimmed to a brief comment. Note: Image redlinks should not be removed
  2. Redlinks to articles unlikely to be created on Wikidwelling can be unlinked. (leave links to locations and institutions.)
  3. Categories may need to be adapted or removed - e.g. "people born in the 1940s". Redlinked categories are not a problem.
  4. Templates not used on Wikidwelling should be deleted, like all the interwiki links ({{de:...}}, {{fr:...}},
  5. When these first tasks are basically done, you can remove this template, writing {{Attrib Wikipedia | article name}} in place of this {{Attrib Wikipedia raw | article name}} at the bottom (simply remove "raw").
    You can also:
  6. Move to a section "External links" all Wikimedia project-related templates (e.g. {{Commons}}, {{Commons category}}, {{Wiktionary}}, etc. ).
  7. Add more specific content (related to the Wikidwelling topic) to the article, insert videos from YouTube, etc.
