Pointed arches form the rib vaults of Worcester Cathedral (1084–1504) A pointed arch, ogival arch, or Gothic arch is an arch with a pointed crown meet at an angle at the top of the arch. [1] Also known as a two-centred arch, its form is derived from the intersection of two circles. [2]
Construction of a four-centred arch. A four-centred arch (Commonwealth spelling) or four-centered arch (American spelling) is a low, wide type of arch with a pointed apex.Its structure is achieved by drafting two arcs which rise steeply from each springing point on a small radius, and then turning into two arches with a wide radius and much lower springing point.
If one impost is much higher than another, the arch (frequently pointed) is known as ramping arch , raking arch, [87] or rampant arch (from French: arc rampant). [88] Originally used to support inclined structures, like staircases , in the 13th-14th centuries their appeared as parts of flying buttresses used to counteract the thrust of Gothic ...
Romanesque architecture is an architectural style of medieval Europe that was predominant in the 11th and 12th centuries. [1] The style eventually developed into the Gothic style with the shape of the arches providing a simple distinction: the Romanesque is characterized by semicircular arches, while the Gothic is marked by the pointed arches.
A very narrow, steeply pointed ogive arch is sometimes called a "lancet arch". The most common form is an equilateral arch , where the radius is the same as the width. In the later Flamboyant Gothic style, an " ogee arch ", an arch with a pointed head, like S-shaped curves, became prevalent.
The use of the pointed arch in turn led to the development of the pointed rib vault and flying buttresses, combined with elaborate tracery and stained glass windows. [ 3 ] At the Abbey of Saint-Denis , near Paris, the choir was reconstructed between 1140 and 1144, drawing together for the first time the developing Gothic architectural features.
The pointed arch had long been known and employed, on account of its much greater strength and of the lessened thrust it exerted on the walls. When employed for the ribs of a vault, however narrow or wide the span might be, by adopting a pointed arch, its summit could be made to match the height of the diagonal ribs. [13]
Analogies between the hanging chains and standing structures: an arch and the dome of Saint Peter's Basilica in Rome (Giovanni Poleni, 1748). In architecture, the funicular curve (also funicular polygon, funicular shape, from the Latin: fūniculus, "of rope" [1]) is an approach used to design the compression-only structural forms (like masonry arches) using an equivalence between the rope with ...
