flying buttress
Noun: A specific type of architectural support, a flying buttress is an arched masonry structure that extends from an upper part of a wall (typically of a large building like a church or cathedral) to a freestanding pier or buttress. This design allows it to channel the outward thrust from a roof or vault away from the main wall to the external support, enabling the construction of taller, thinner walls with large windows.
The term flying buttress is used specifically in the context of architecture, particularly when describing Gothic cathedrals and other large stone buildings. It refers to the visible, arched support structure on the exterior.
Examples: * The flying buttress is a defining feature of Gothic architecture. * Architects used flying buttresses to support the immense weight of the cathedral's stone vaults. * The intricate stonework of the flying buttress is both functional and decorative.
- Structural Role: The primary function is to counteract lateral forces (sideways thrust). The arch of the flying buttress transfers the force from the high wall to the external pier, which is grounded.
- Historical Significance: The development of the flying buttress in the 12th century was crucial for the Gothic architectural revolution, allowing for the construction of soaring naves and expansive stained-glass windows.
- Buttress (noun): A broader term for any projecting support built against a wall to strengthen it. A flying buttress is a specific kind of arched buttress.
- Pier buttress (noun): The solid, vertical support column on the ground that receives the thrust from the flying buttress's arch.
- Arc-boutant (noun): The French term from which "flying buttress" is derived, meaning "arching buttress."
- Gothic architecture (noun phrase): The architectural style most famously associated with the use of flying buttresses.
- Lateral thrust (noun phrase): The sideways force that a flying buttress is designed to resist.
- Vault (noun): The arched stone ceiling whose weight and outward push often necessitate the use of flying buttresses.
