Pointed archA pointed arch, ogival arch, or Gothic arch is an arch with a pointed crown, whose two curving sides meet at a relatively sharp angle at the top of the arch. Also known as a two-centred arch, its form is derived from the intersection of two circles. This architectural element was particularly important in Gothic architecture. The earliest use of a pointed arch dates back to bronze-ageNippur.
VoussoirA voussoir (UK: ; US: ) is a wedge-shaped element, typically a stone, which is used in building an arch or vault. Each voussoir is formed in a specific way to fit within the arch or vault created. Normally, different colored stones are shaped to fit together in a curved way that relies on the balance of each other to stay in place.
Roman brickRoman brick is a type of brick used in ancient Roman architecture and spread by the Romans to the lands they conquered, or a modern adaptation inspired by the ancient prototypes. Both types are characteristically longer and flatter than standard modern bricks.
ArchAn arch is a curved vertical structure spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century BC. Arch-like structures can be horizontal, like an arch dam that withstands a horizontal hydrostatic pressure load.
ArchitectureArt and technique of designing buildingsIn adding the dome to the Florence Cathedral (Italy) in the early 15th century, the architect Filippo Brunelleschi not only transformed the building and the city, but also the role and status of the architect.Bauhaus building (Germany). The Bauhaus style co-started modernist architecture.Architecture is the study and practice of designing structures, especially habitable ones.
Ancient Roman architectureAncient Roman architecture adopted the external language of classical ancient Greek architecture for the purposes of the ancient Romans, but was different from Greek buildings, becoming a new architectural style. The two styles are often considered one body of classical architecture. Roman architecture flourished in the Roman Republic and to an even greater extent under the Empire, when the great majority of surviving buildings were constructed.
Parabolic archA parabolic arch is an arch in the shape of a parabola. In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms.
Span (engineering)In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span). For a bridge, the total span is the distance between the faces of the abutments: A span can be closed by a solid beam or by a rope.
SemicircleIn mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. It is a circular arc that measures 180° (equivalently, π radians, or a half-turn). It only has one line of symmetry (reflection symmetry).
Ancient RomeIn modern historiography, ancient Rome is the Roman civilisation from the founding of the Italian city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (509–27 BC), and the Roman Empire (27 BC – 476 AD) until the fall of the western empire.*As an Amazon Associate I earn from qualifying purchases.
