A hyperbolic paraboloid ... This figure shows a finite portion of a hyperbolic paraboloid. Its equation is fairly simple, namely z = xy. Thus, it is a smooth quadric surface. ... ; A few buildings have been constructed with a roof in the shape of a hyperbolic paraboloid. Click here to see pictures of one of these.

Saddle roof - Wikipedia, the free encyclopedia
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 const...

The tied beam carries axial forces transmitted to it from the curved shell roof of hyperbolic paraboloid. In the computer stability analysis with finite element model, the interaction between hyperbolic paraboloidal roof, tied beams, and columns should be taken into account.
