The term "fly buttress" refers to a specific architectural element commonly found in Gothic-style cathedrals and other large-scale buildings. A fly buttress is a structure composed of a vertical support buttress, often square or rectangular in shape, that extends upwards from the ground. It typically possesses an inclined or diagonal bridge-like projection, known as a flying arch or flyer, that connects the upper part of the buttress to the wall of the building it supports.
The primary function of a fly buttress is to provide additional stability and support to the walls of a structure, particularly where large openings such as windows are present. By transferring the lateral forces created by the weight of the roof or upper walls to the ground, fly buttresses help to counteract the outward pressure exerted on the main walls and prevent them from collapsing or deforming under the building's weight.
Fly buttresses are distinguished by their unique combination of functionality and aesthetic appeal. They often feature intricate carvings, decorative embellishments, or statues adorning their surfaces, showcasing the artistic craftsmanship prevalent in Gothic architecture. Moreover, the distinct silhouette created by the combination of vertical buttresses and flying arches lends an iconic and distinctive character to these structures.
In summary, a fly buttress refers to an architectural element that adds stability, strength, and visual interest to a building, particularly Gothic-style constructions. Its vertical support buttress, combined with an inclined flying arch, helps redistribute the weight and pressure, maintaining the overall structural integrity and preventing the collapse of the main walls.
