Hypar Roof Structures

The hypar thin shell concrete roof is a roofing system developed by george nez and albert knott of tsc global who trained groups in several developing countries in how to construct them.

Hypar roof structures.

One of the groups they trained is technology for tomorrow t4t who is offering the roofs as a building product in uganda. These type of structure is commonly found in sports facilities warehousing and storage buildings and exhibition venues. Cantilevers are 230 ft. In warmer climates these roofs should last many decades.

Sometimes referred to as a hypar the saddle roof may also be formed as a tensegrity structure. This is the same type of roof used on the free burma ranger clinic posted earlier. Built on a module design the roof currently has eight pairs of balanced hypars. A tensile membrane structure is most often used as a roof as they can economically and attractively span large distances.

Mathematically a saddle shape contains at least one saddle point. This twist produces the hypar form while opposing tension forces keep the canopy membrane tight across the span. In this article we briefly discuss the types shapes. Hyperboloid structures are architectural structures designed using a hyperboloid in one sheet.

The historical meaning is a synonym for a gable roof particularly a dual pitched roof on a tower also called a pack saddle roof. George nez pioneered and wrote the book on hypar roofs along with albert knott. Often these are tall structures such as towers where the hyperboloid geometry s structural strength is used to support an object high off the ground but hyperboloid geometry is also often used for decorative effect as well as structural economy. The bottom of the roof is 80 ft.

The hypar roof became candela s trademark. Utilising the hyperbolic paraboloid orion hypar fabric canopies are probably the simplest of all tensile structures with a distinctive shape created when the diagonally opposite corners of a sail are raised. They re extremely durable and practical and have been used around the world for decades. His bread and butter structure was the canopy roof says maria garlock professor of civil and environmental engineering at princeton.

Hypar roofs are lightweight enough they can be built on the ground and lifted into place. The umbrellas line the coast and remain upright during normal operation providing shade and shelter along the waterfront while not limiting access to the shore. This double cantilever roof structure consists of a series of hypar shells made of this steel decking. Maximum to 4 ft.

Wide and have a depth that tapers from 40 ft.
