By sustaining the clerestory and the weight of the high roofs, the flying buttress initially helped convey the concept of open space and light to the cathedrals via solidity and construction. But as architects improved their techniques, the need for the flying buttress became less apparent.
The true importance of the flying buttress is that it provided a way for the architect to achieve stability in a tall building. The buttress did this by providing lateral support that would have been difficult or impossible to provide otherwise. For example, without the use of the flying buttress, the central tower of St. Peter's Cathedral in Rome would not have been able to rise more than four stories before it began to lean toward the west under its own weight.
As long as there are winds outside the building, then some part of the structure will be expected to flex or bend in order to maintain equilibrium. But if the lateral supports are too weak, then further increases in height will cause the tower or roof to collapse.
The flying buttress allows for greater heights because it provides additional strength where it is needed most - laterally across from the main thrust of the building.
After the Renaissance, when the emphasis shifted away from open spaces to more enclosed designs, the need for the flying buttress diminished further.
Flying buttresses are a type of architectural element that is commonly seen in medieval cathedral designs. Flying buttresses are formed by protruding from the walls of a structure down to the foundation in a half-arced shape, which was first established in Romanesque architecture and then refined in Gothic architecture. The purpose of flying buttresses is to increase the lateral strength of the wall without increasing its weight too much. They also act as decorative features by allowing the sculptor to show off his or her talent.
When the Renaissance came along, it was thought that the ancient world had been wrong about many things including the use of flying buttresses. It was believed that the Greeks and Romans must have been mistaken about these structures being useful because there were no flying buttresses in classical architecture. However, this idea was changed when Andrea Palladio published his book "I Quattro Libri dell'Architettura" in 1570. In this book, he states that flying buttresses are necessary for strong buildings especially in regions with high winds such as in Italy. His opinion on this matter has proved to be accurate since many modern buildings in Europe and America include flying buttresses.
Even though Romanesque architects did not use flying buttresses, they would still use other methods to strengthen their buildings. For example, they would often insert large blocks of stone into the walls to increase its strength.
Flying buttresses were utilized in many Gothic churches; they allowed architects to erect very tall but comparably thin stone walls, allowing stained-glass windows to cover most of the wall space. The generally semicircular space encompassed by the arch above the lintel of an arched entry door. Also called keystone window or simply buttress.
The word "buttress" comes from the French word "bottre," which means "a support for something heavy." In architecture, a buttress is used to strengthen an exterior wall structure against pressure forces such as those caused by wind loads or seismic activity. It consists of a vertical column set back from the face of the wall with an enlarged base for stability. The purpose of this study guide is to provide you with an overview of the major types of buttresses found in Gothic architecture and their purposes.
There are two basic types of buttresses: natural and artificial. Artificial buttresses are made of concrete or steel and are added to existing buildings while natural buttresses occur naturally within the rock itself. Although both types of buttresses help to stabilize buildings, they serve different functions. Natural buttresses provide extra strength where there is no available material so designers often incorporate natural features into structures to increase stability. For example, half-timbering—the use of timber that has been exposed on one side only—is commonly found in regions where wood is scarce because it saves weight and costs money to build with.
The flying buttress was a pivotal architectural innovation developed by these builders: by efficiently transferring thrust from specific points on the upper walls of Gothic buildings to far-removed supports, the flying buttress enabled these builders to transform, over the course of the late-twelfth century, an architecture dominated by solid stone walls and flat roofs into one where voids and openings were increasingly incorporated into building design. The flying buttress allowed architects to create more complex structures while still maintaining the appearance of strength and stability. It also provided additional space for housing offices and services within the building.
How did they know how to build them? Did any builders learn their trade abroad?
No. All information about buttressing techniques and materials was passed on from builder to apprentice through oral tradition within the guilds. No foreign builders are known to have worked in Gothic Europe. However, French builders working in England during the early years of the English Gothic style may have learned how to construct flying buttresses from their English colleagues; later, when French builders began working on projects in Germany and Austria, they probably took this technology with them.
What is special about German wood? How did it become so popular for building ships?
German wood is well-suited for shipbuilding because of its light weight and high tensile strength.
Buttresses have historically been used to reinforce massive walls or buildings, such as cathedrals. Flying buttresses are made comprised of an inclined beam borne on a half arch that projects from a structure's walls to a pier that supports the weight and horizontal thrust of a roof, dome, or vault. These beams provide additional structural support for heavy roofs and allow for more open space inside the building.
Flying buttresses were first used in Europe during the 13th century. They were invented by French architect Guillaume Hugon, who was also one of France's earliest architects. He used them to increase the size of churches that he designed while keeping their costs down by avoiding expensive stone masonry.
In architecture, a flying buttress is a type of architectural detail that provides additional support for a wall or roof. The term is generally applied to any of several types of projecting structures found on medieval and Renaissance buildings that serve similar purposes. They differ mainly in shape and material, but all act as bracing for interior walls or floors beneath which they often carry ceilings or roofs.
Buttressing was originally used to protect weak areas of a building or structure where damage could occur without destroying its overall appearance. For example, ancient buildings with thick walls were usually buttressed to show where the wall was thinnest. Modern buildings with thin walls are sometimes buttressed to indicate where the walls meet up and to provide some extra strength in those areas.
