What advantages does the use of pendentives give a building or plan?

One of the earliest examples of pendentives can be found in Hagia Sophia, a structure in Istanbul, Turkey that was built around 537 AD. Solving the issue more gracefully than squinches, pendentives allowed for greater height and an increasing sense of lightness in spaces.

How do pendentives work?

In architecture, a pendentive is a constructional device permitting the placing of a circular dome over a square room or of an elliptical dome over a rectangular room. 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.

How did the Byzantines build a pendentive?

Byzantine engineers turned to the structural use of pendentives to elevate domes to new heights. With this technique, a dome can rise from the top of a vertical cylinder, like a silo, giving height to the dome.

How are arch the vault and the dome all related to each other?

How are the arch, the vault and the dome all related to one another? True arches are curved. A vault is an arched ceiling or roof of stone, brick or concrete, sometimes imitated in wood or plaster. A dome is a vault of even curvature on a circular base.

What is a vault describe its parts and functions?

A vault is an arched structure that springs from a cornice, which is supported by both a solid wall and four columns. The cornice is a set of projecting moldings that crown the top edge of a temple or building. Vaults provide increased space in the ceiling and create a self-formed roof for a building.

What are pendentives domes?

Pendentive is the term given to a construction element that allows a dome to be placed over square or rectangular spaces. The pendentives receive the outward force from the dome’s weight and concentrate it at the four corners where it is directed down the columns to the foundations beneath. …

Where are pendentives found?

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.

What makes Byzantine architecture impressive?

Byzantine architects were eclectic, at first drawing heavily on Roman temple features. Byzantine structures featured soaring spaces and sumptuous decoration: marble columns and inlay, mosaics on the vaults, inlaid-stone pavements, and sometimes gold coffered ceilings.

What is a pendentive in architecture?

Encyclopaedia Britannica/UIG/Getty Images (cropped) Dr. Jackie Craven has over 20 years of experience writing about architecture and the arts. She is the author of two books on home decor and sustainable design. A pendentive is a triangular piece beneath a dome that allows the dome to rise high above the floor.

What is a pendentive dome used for?

Pendentives are used for stabilizing a round dome on a square frame, resulting in enormous interior open space beneath the dome. The Dictionary of Architecture and Construction defines a pendentive as “One of a set of curved wall surfaces which form a transition between a dome (or its drum) and the supporting masonry.”.

What is the difference between a squinch and a pendentive?

The use of four squinches turns a square into an octagon to support the dome, but they have a blocky appearance. A pendentive is more elegant, like a spherical triangle. Transitioning from the square corners of the room, four pendentives arch inward to meet the circular base of a dome. They allow greater height and a sense of weightlessness.

How many pendentive areas could tell a visual story?

Four pendentive areas could tell a visual story. More than anything, however, pendentives tell the real story of architecture. Architecture is about solving problems. For early Christians the problem was how to create soaring interiors that expresses man’s adoration of God. Architecture also evolves over time.
