rib vault | Definition, History, & Facts

rib vault, besides called ribbed vault, in build construction, a skeleton of arches or ridicule on which masonry can be laid to form a ceiling or roof. Rib vaults were frequently used in chivalric buildings, most famously in Gothic cathedrals. similarly to groin vaults, ridicule vaults are constructed from two, sometimes three, intersecting vaults, which can be of different widths but must be of the same acme. The medieval mason used pointed arches—probably adopted from Islamic architecture in Spain. Unlike the beat arches used in Romanesque cathedrals, pointed arches could be raised as high over a short span as over a long one. The arches are located at the joints of the vaults and carry the weight of the ceiling.

The rib vault arose out of medieval masons ’ efforts to solve the challenges associated with supporting heavy masonry ceiling vaults over wide-eyed spans. The problem was that the heavy stonework of the traditional arched barrel vault and the groin vault exerted a fantastic down and outbound pressure that tended to push the walls upon which the vault rested outward, therefore collapsing them. A build ’ randomness vertical supporting walls thus had to be made extremely blockheaded and heavy in order to contain the barrel vault ’ s outward pierce. consequently, windows were few and humble in Romanesque churches, and interiors were iniquity and big. medieval masons solved the problem about 1120 with a numeral of bright innovations—first and first, the rib vault. The arch and intersecting stone rib support a vaulted ceiling surface that is composed of mere thin gem panels. This greatly reduced the slant ( and therefore the outward force ) of the ceiling vault, and, since the vault ’ s weight was nowadays carried at discrete points ( the rib ) preferably than along a continuous wall edge, separate widely spaced vertical piers to support the rib could replace the continuous thick walls. The round arches of the barrel vault were replaced by point ( Gothic ) arches, which distributed jab in more directions down from the topmost point of the arch .four common types of vaultfour common types of vault Four common types of vault. A barrel vault ( besides called a cradle vault, tunnel vault, or wagon vault ) has a semicircular hybridization department. A breakwater ( or cross ) vault is formed by the vertical intersection of two barrel vaults. A ridicule ( or ribbed ) vault is supported by a series of arced aslant rib that divide the vault ‘s surface into panels. A sports fan vault is composed of concave sections with ribs spreading out like a fan.

© Merriam-Webster Inc. Decades of experiment produced vaulting that was light, hard, open, versatile, and applicable everywhere. Combined with such other innovations as flying buttresses, rib vaults allowed Gothic buildings to become, in succession, broader and grandiloquent. How their ocular appearance changed is easy to see if one compares, for case, the tall and airy 13th-century Reims Cathedral in France with the portly 11th-century Durham Cathedral in England.
