lancet arch

Examples of lancet arch in the following topics:

• Renaissance Architecture in Venice

  • Venetian Gothic architecture is a term given to a Venetian building style combining use of the Gothic lancet arch with Byzantine and Ottoman influences.
  • The large arch in the center is known as the porta regia or "royal arch."

• Gothic Cathedrals

  • One of the defining characteristics of Gothic architecture is the pointed or ogival arch.
  • The way in which the pointed arch was drafted and utilized developed throughout the Gothic period, and four popular styles emerged: the Lancet arch, the Equilateral arch, the Flamboyant arch, and the Depressed arch.
  • Gothic openings such as doorways, windows, arcades, and galleries have pointed arches.
  • Niches with pointed arches that contain statuary are a major external feature.
  • Ogival, or pointed arches, increased in popularity in the Gothic period.

• English Gothic Architecture

  • English Gothic architecture (c. 1180–1520) is defined by pointed arches, vaulted roofs, buttresses, large windows, and spires.
  • This style is defined by pointed arches, vaulted roofs, buttresses, large windows, and spires.
  • The most significant characteristic development of the Early English period was the pointed arch known as the lancet.
  • Compared with the rounded Romanesque style, the pointed arch of the Early English Gothic is aesthetically more elegant and is more efficient at distributing the weight of stonework, making it possible to span higher and wider gaps using narrower columns.
  • Using the pointed arch, walls could become less massive and window openings could be larger and grouped more closely together, so architects could achieve more open, airy, and graceful buildings.

• Italian Architecture 1200-1400

  • Gothic architecture was developed in France and was characterized by lancet, or pointed, archways used for both windows and doorways.
  • The interior of the Cathedral, including the groin vaults and pointed arches, demonstrates the Gothic elements of its architecture quite clearly.

• Architecture

  • Massive cylindrical piers, groin vaults and low-relief sculptural decoration support rounded arches, arcades, characterize Romanesque churches.
  • The desire to increase window space drove the development of new structural techniques, which constitute most of the other distinctive features of the style: pointed arches, rib vaults, buttresses and pinnacles.
  • It is typified by the simplicity of its vaults and tracery, the use of lancet windows and smaller amounts of sculptural decoration than either Romanesque or later varieties of Gothic.

• Arches, Vaults, and Domes

  • This is sometimes referred to as arch action.
  • As the forces in the arch are carried to the ground, the arch will push outward at the base; this is called thrust.
  • Circular arches, also referred to as rounded arches, were commonly employed by the builders of ancient, heavy masonry arches.
  • The advantage of using a pointed arch rather than a circular arch is that the arch action in a pointed arch produces less thrust at the base.
  • Of any arch type, the parabolic arch produces the most thrust at the base, but can span the largest areas.

• Arch of the Aorta

  • The arch of the aorta follows the ascending aorta and begins at the level of the second sternocostal articulation of the right side.
  • The arch of the aorta, or the transverse aortic arch, is continuous with the upper border of the ascending aorta and begins at the level of the upper border of the second sternocostal articulation of the right side.
  • Three vessels come out of the aortic arch: the brachiocephalic artery, the left common carotid artery, and the left subclavian artery.
  • In approximately 20% of individuals, the left common carotid artery arises from the brachiocephalic artery rather than the aortic arch, and in approximately 7% of individuals the left subclavian artery also arises here.
  • This diagram shows the arch of the aorta and its branches.

• Arches and Domes

  • As the forces in an arch are carried toward the ground, the arch will push outward at the base (called thrust).
  • As the height of the arch decreases, the outward thrust increases.
  • The most common true arch configurations are the fixed arch, the two-hinged arch and the three-hinged arch.
  • The two-hinged arch is most often used to bridge long spans.
  • This type of arch has pinned connections at the base.

• Arches of the Feet

  • The arches of the foot are formed by the tarsal and metatarsal bones.
  • The longitudinal arch of the foot can be broken down into several smaller arches.
  • The main arches are the antero-posterior arches, which may, for descriptive purposes, be regarded as divisible into two types—a medial and a lateral.
  • In contrast, the lateral longitudinal arch is very low.
  • In addition to the longitudinal arches, the foot presents a series of transverse arches.

• Development of the Cardiovascular System

  • The aortic arches or pharyngeal arch arteries are a series of six paired, embryological vascular structures which give rise to several major arteries .
  • The third aortic arch constitutes the commencement of the internal carotid artery, and is named the carotid arch.
  • The fourth left arch constitutes the arch of the aorta between the origin of the left carotid artery and the termination of the ductus arteriosus.
  • The fifth arch disappears on both sides.The proximal part of the sixth right arch persists as the proximal part of the right pulmonary artery, while the distal section degenerates.
  • A double aortic arch occurs with the development of an abnormal right aortic arch, in addition to the left aortic arch, forming a vascular ring around the trachea and esophagus, which usually causes difficulty breathing and swallowing.
