Paraboloid Roof Structure

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.

A hyperbolic paraboloid not to be confused with a hyperboloid is a doubly ruled surface shaped like a saddle in a suitable coordinate system a hyperbolic paraboloid can be represented by the equation. Tests on a one tenth scale model of a hyperbolic paraboloid shell roof. Although the hyperbolic paraboloid is curved in two directions it is composed entirely of straight lines.

Gallery of more hyperbolic paraboloid structures the hyperbolic paraboloid is a doubly ruled surface and thus can be used to construct a saddle roof from straight beams. A hyperbolic paraboloid roof is a configuration which has esthetic structural and economic advantages for many purposes as for example inexpensive attractive large area structures free of. A saddle roof is a roof form which follows a convex curve about one axis and a concave curve about the other. In this position the hyperbolic paraboloid opens downward along the x axis and upward along the y axis that is the parabola in the plane x 0 opens upward and the parabola in.

Mathematically a saddle shape contains at least o. The growing popularity of this roof is rooted in a seemingly contradictory characteristic of its shape. International journal of space structures v. However a the hyperbolic paraboloid as a thin shell roof type is making inroads in these markets.

Sometimes referred to as a hypar the saddle roof may also be formed as a tensegrity structure. He is celebrated for his feats of architectural engineering that transform concrete into visual poetry with his structural design based on hyperbolic paraboloid geometric form. Wind and seismic stresses in hyperbolic paraboloid shells. His work with thin shell concrete roof structures broke barriers between architecture and engineering that opened the way for other architects such as santiago calatrava.

Hyperbolic paraboloid shell roofs can be constructed using reinforced concrete with a shell thickness of just 50 mm for diagonal spans up to 35 m.
