Hyperbolic paraboloid roof structure.

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 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. Model is made of bamboo and hot glue quick and dirty. In the sagrada família there are a few places on the nativity facade a design not equated with gaudi s ruled.

However a the hyperbolic paraboloid as a thin shell roof type is making inroads in these markets. The growing popularity of this roof is rooted in a seemingly contradictory characteristic of its shape. The term is used because the form resembles the shape of a saddle.

A roof structure for a hanger or the like in which first and second roof sections having the shapes of parts of respective first and second hyperbolic paraboloids having common base lines are joined along a line lying on the locus of an arch common to the two paraboloids to form a roof having openings of predetermined height between spaced roof supports.

Although the hyperbolic paraboloid is curved in two directions it is composed entirely of straight lines. Sometimes referred to as a hypar the saddle roof may also be formed as a tensegrity structure. An important aspect about the aerodynamic behavior of hyperbolic paraboloid roofs is the presence of conical vortices. Curvilinear steel bar structures forming roofs of hyperbolic paraboloid 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.
