Hyperbolic paraboloid roof structure.

Curvilinear steel bar structures forming roofs of hyperbolic paraboloid shape. Although the hyperbolic paraboloid as a ruled surface may be a convenient base for forming bar grids there are few studies on the e ect of its division and the topology of the obtained bar structures on their load bearing capacity. In the sagrada família there are a few places on the nativity facade a design not equated with gaudi s ruled. It is also a doubly ruled surface that is every point on its surface.

Finally insights on wind structure interaction and dynamic effects on hyperbolic paraboloid roofs is available in yang et al. 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. An important aspect about the aerodynamic behavior of hyperbolic paraboloid roofs is the presence of conical vortices. Explore amanda sexton s board hyperbolic paraboloid architecture on sketch shell structure architecture design contemporary architecture architecture.

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. Antoni gaudi used structures in the form of hyperbolic paraboloid hypar and hyperboloid of revolution in the sagrada família in 1910. Hyperbolic paraboloid in construction designing buildings wiki share your construction industry knowledge. Creating a model for a hyperbolic paraboloid sculpture.

And in sun et al. Antoni gaudi and shukhov carried out experiments with hyperboloid structures practically simultaneously but independently in 1880 1895. This paper concerns the design calculations and construction of a hyperbolic paraboloid steel shell structure used as a roof for an. 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. Although the hyperbolic paraboloid is curved in two directions it is composed entirely of straight lines. The growing popularity of this roof is rooted in a seemingly contradictory characteristic of its shape. Model is made of bamboo and hot glue quick and dirty.
