Hypar Roof Structures

The historical meaning is a synonym for a gable roof particularly a dual pitched roof on a tower also called a pack saddle roof.

Hypar roof structures. Built on a module design the roof currently has eight pairs of balanced hypars. They re extremely durable and practical and have been used around the world for decades. A tensile membrane structure is most often used as a roof as they can economically and attractively span large distances. This twist produces the hypar form while opposing tension forces keep the canopy membrane tight across the span.

Sometimes referred to as a hypar the saddle roof may also be formed as a tensegrity structure. The hypar roof became candela s trademark. Hypar structures have been built for decades but the most closely observed demo structure was built in boulder in 1996 enduring colorado freezes thaws winds and up to 3 feet of snow and is in near perfect condition after 14 years. 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.

The bottom of the roof is 80 ft. George nez pioneered and wrote the book on hypar roofs along with albert knott. 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. 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.

His bread and butter structure was the canopy roof says maria garlock professor of civil and environmental engineering at princeton. Wide and have a depth that tapers from 40 ft. Mathematically a saddle shape contains at least one saddle point. Hypar roofs are lightweight enough they can be built on the ground and lifted into place.

One of the groups they trained is technology for tomorrow t4t who is offering the roofs as a building product in uganda. In warmer climates these roofs should last many decades. Hyperboloid structures are architectural structures designed using a hyperboloid in one sheet. Abstract this paper introduces an innovative structural system consisting of four sided hyperbolic paraboloid hypar roof umbrellasas hard countermeasures against nearshore hazards.

These type of structure is commonly found in sports facilities warehousing and storage buildings and exhibition venues. A tensile structure is a structure elements carrying only tension and no compression or bending. In this article we briefly discuss the types shapes. Maximum to 4 ft.

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.
