Buttress
A buttress is a structural architectural element built against or projecting from a wall to provide support and reinforcement. Its primary function is to counteract lateral forces, such as the outward thrust from a heavy roof, vault, or arch, by transferring these loads directly to the ground. While buttresses are essential for structural stability and allow for taller walls with larger openings, they also serve an aesthetic purpose, particularly in Gothic and Romanesque architecture where they define the building's exterior character. Common variations include the flying buttress, which uses an arched bridge to connect a wall to an external pier, and various corner designs like angled, clasping, and setback buttresses.
Frequently Asked Questions
Why is buttress important in architecture?
A buttress is a structural element built against or projecting from a wall to provide support and reinforcement. It is important because it counteracts lateral forces, such as the outward thrust from a roof or vault, transferring these loads to the ground to prevent walls from buckling or collapsing and allowing for taller structures with thinner walls and larger openings.
What are the different types of buttress?
Common types of buttresses include ordinary or pier buttresses, flying buttresses, and various corner designs such as angled, clasping, diagonal, and setback buttresses. Other specialized forms include hanging buttresses, scroll buttresses, and thick Earthquake Baroque buttresses, all designed to counteract lateral forces and reinforce structural stability.
What materials are commonly used for a buttress, and how do they impact durability and cost?
A buttress is a structural architectural element built against or projecting from a wall to provide essential support and reinforcement. It functions by counteracting lateral forces—such as the outward thrust from a heavy roof, vault, or arch—and transferring these loads directly to the ground to prevent walls from buckling or collapsing. This support allows for taller structures with thinner walls and larger window openings. Beyond their structural necessity in masonry buildings, buttresses can also serve as decorative features that define a building's rhythm and aesthetic identity.
