Large structures Hinges appear in large structures such as elevated freeway and railroad viaducts. These are included to reduce or eliminate the transfer of bending stresses between structural components, typically in an effort to reduce sensitivity to earthquakes.

Raised Floor Design Many modern computer and equipment rooms employ an underfloor air distribution to ensure even cooling of the room with minimal wasted energy. Conditioned air is provided under the floor and dispersed upward into the room through regularly spaced diffuser tiles, blowers or through ducts directed into specific
Woven Wire Another variant on woven wire is the hog panel, which consists of heavy welded wire approximately .25 inches (6 mm) or more in diameter. It resembles field fence in appearance, but is sold in panels rather than rolls and is not easily wrapped or bent. However, larger livestock such
Raised Floor Design Additionally, when buildings are designed to combine modular electrical, modular walls, and access floor, the space within the building can be reconfigured in a few hours, as compared to historical means of demolishing walls and drilling holes in the floor to route electrical and other services.

Floating floors as used in sound studios can be either just larger versions of the domestic variety, or much larger constructions with slabs of concrete to keep the resonance frequency down. The manufacture of integrated circuits uses massive floating floors with hundreds of tons in weight of concrete to avoid
Wood, Pipe and Other Materials Fences of wood, stranded cable, and pipe are used where cost is less of a consideration, particularly on horse farms, or in pens or corrals where livestock are likely to challenge the fence. Synthetic materials with wood-like qualities are also used, though they are the most
Glass Flooring A German manufacturer of squash court floors has diversified into making glass floors for other sports, such as basketball. Their glass floors usually are translucent rather than transparent, and the line markings are indicated by illumination with LEDs below the floor. On occasion, transparent display cases are built into
