“pendentive”的意思、由来-百科全书

pendentive

architecture

in architecture, a triangular segment of a spherical surface, filling in the upper corners of a room, in order to form, at the top, a circular support for a dome. The challenge of supporting a dome over an enclosed square or polygonal space assumed growing importance to the Roman builders of the late empire. It remained for Byzantine architects, however, to recognize the possibilities of the pendentive and fully develop it. One of the earliest examples of the use of the pendentive is also one of the largest—that of Hagia Sophia (completed AD 537) at Istanbul.

Pendentives are common in the Romanesque domed churches of the Aquitaine in France, as in Saint-Front at Perigueux (begun 1120) and the cathedral of Saint-Pierre at Angoulême (1105–28), but they occur only occasionally in Italian churches. During the Renaissance and the Baroque the preference for domed churches, especially in Roman Catholic Europe and Latin America, gave great importance to the pendentive. As a result of Byzantine influence, pendentives are frequently used in Islamic architecture. They are often decorated with stalactite work or sometimes, as in Iran, with delicate ribbing.

A vaulting form in which the curve of the pendentive and dome is continuous, without a break, is known as a pendentive dome. See also dome; squinch.
