What is a spandrel glass?
Unlike vision glass, which is meant to be transparent, spandrel glass is a non‑vision application designed to be opaque in order to help obscure the spaces between the floors of a building, including insulation, vents, wires, slab ends and mechanical equipment.
What is the use of spandrel?
Spandrel beams are load-bearing structural members around the perimeter of a floor of a building. Not only may they support loads from the roof and other floors, they may also help support a building’s walls.
What is a spandrel in geometry?
A spandrel is a roughly triangular space, usually found in pairs, between the top of an arch and a rectangular frame; between the tops of two adjacent arches or one of the four spaces between a circle within a square. They are frequently filled with decorative elements.
Where is spandrel glass used?
Unlike vision glass, which is meant to be transparent, spandrel glass is designed to be opaque in order to help hide features between the floors of a building, including vents, wires, slab ends and mechanical equipment.
What is spandrel material?
Spandrel panels are also known as infill panels, or insulated aluminum composite panels. They are commonly used to infill areas of glazing curtain walls or storefronts. They take the place of 1″ or 1/4″ thick glass units.
What is an example of an Exaptation?
Exaptation is the process of adaptation of a trait for a purpose other than what the trait was evolved for. For instance, an exaptation could be the use of feathers for mating displays or flight in birds which evolved feathers originally to keep warm.
What is spandrel made of?
Spandrels come in different materials, but the most common ones are wood, vinyl, fiber cement, and metal.
What is spandrel area?
spandrel, also spelled spandril, the roughly triangular area above and on either side of an arch, bounded by a line running horizontally through the apex of the arch, a line rising vertically from the springing of the arch, and the curved extrados, or top of the arch.
What is an exaptation example?
Exaptation is the process of adaptation of a trait for a purpose other than what the trait was evolved for. For instance, an exaptation could be the use of feathers for mating displays or flight in birds which evolved feathers originally to keep warm. An exaptation is also known as pre-adaptation.
What is the difference between preadaptation and exaptation?
For Gould and Vrba (1982), pre-adaptation refers solely to features that promote fitness and were built by selection to perform the same function for which they originally evolved, while features that evolved for other usages or for no function at all and were co-opted for their current role at a later point in time …
What is the difference between exaptation and preadaptation?
What does spandrel mean in psychology?
In the context of evolution, they introduced the term spandrel as a metaphor for characteristics that are or were originally side effects and not true adaptations to the environment. They are traits which confer no adaptive advantage to an organism, but are ‘carried along’ by an adaptive trait.
