Sometimes referred to as a hypar the saddle roof may also be formed as a tensegrity structure. A saddle roof is a roof form which follows a convex curve about one axis and a concave curve about the other. Mathematically a saddle shape contains at least o.

The growing popularity of this roof is rooted in a seemingly contradictory characteristic of its shape. A hyperbolic paraboloid sometimes referred to as h p is a doubly curved surface that resembles the shape of a saddle that is it has a convex form along one axis and a concave form on along the other. A hyperbolic paraboloid is a saddle surface as its gauss curvature is negative. It was architecture of the future with its distinctive bent upwards peaked ends the front facing one usually more prominent and supports at only two points set back so there s balance to the structure.

It is also a doubly ruled surface that is every point on its surface lies on two straight lines across the surface. This paper concerns the design calculations and construction of a hyperbolic paraboloid steel shell structure used as a roof for an.

Although the hyperbolic paraboloid is curved in two directions it is composed entirely of straight lines. The term is used because the form resembles the shape of a saddle. Mass observation hyperbolic paraboloid roof documents a postwar modern structure in nottingham england that now houses a chain roadside restaurant. The scotiabank saddledome arena has a hyperbolic paraboloid saddle roof calgary canada 1983.

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. Born of this time was the hyperbolic paraboloid roof simply hp roof sometimes saddle roof. The hyperbolic paraboloid is a doubly ruled surface so it may be used to construct a saddle roof from straight beams. In particular pringles fried snacks resemble a truncated hyperbolic paraboloid.

The entire roof structure rests on only two supports giving it an appearance somewhat resembling a bird in flight. Explore amanda sexton s board hyperbolic paraboloid architecture on sketch shell structure architecture design contemporary architecture architecture.
