P0161300 (pĕn-dĕn′tĭv)n. Architecture A three-sided, curved section of vaulting between the rim of a dome and each adjacent pair of the arches that support it.

[French pendentif, from Latin pendēns, pendent-, hanging, present participle of pendēre, to hang; see (s)pen- in Indo-European roots.]

pendentive

(pɛnˈdɛntɪv) n (Architecture) any of four triangular sections of vaulting with concave sides, positioned at a corner of a rectangular space to support a circular or polygonal dome[C18: from French pendentif, from Latin pendens hanging, from pendere to hang]

pen•den•tive

(pɛnˈdɛn tɪv)

n. one of several spandrels, in the form of concave triangles, forming a transition between the circular plan of a dome and the polygonal plan of the supporting masonry. [1720–30; < French pendentif; see pendent, -ive]

Translations

pendentive

pendentive,

in architecture, a constructive device permitting the placing of a circular dome over a square room or an elliptical dome over a rectangular room. The pendentives, which are triangular segments of a sphere, taper to points at the bottom and spread at the top to establish the continuous circular or elliptical base needed for the dome. In masonry the pendentives thus receive the weight of the dome, concentrating it at the four corners where it can be received by the piers beneath. Prior to the pendentive's development, the device of corbeling or the use of the squinchsquinch,
in architecture, a piece of construction used for filling in the upper angles of a square room so as to form a proper base to receive an octagonal or spherical dome.

The first attempts at pendentives were made by the Romans, but full achievement of the form was reached only by the Byzantines in Hagia Sophia at Constantinople (6th cent.). Pendentives were commonly used in Renaissance and baroque churches, with a drum often inserted between the dome and pendentives.

Pendentive

The curved triangular surface that results when the top corner of a square space is vaulted so as to provide a circular base for a dome.

Pendentive

a curved, triangular feature whose purpose is to enable a circular dome or drum to be supported above a square substructure. The top of the triangle is inverted, filling the space between the arches that join the adjacent pillars of the substructure. The bases of the triangles of the pendentives form a circle and distribute the load of the dome along the perimeter of the arches. Being one of the basic structural elements of Byzantine architecture, pendentives were characteristic of ancient Russian churches. They are also seen in domed buildings of the Renaissance and of the 17th, 18th, and 19th centuries.
