Components of An Arch

To construct the arches they erected circular wooden scaffolds or centering. The arch was started simultaneously from both ends of the centering. Wedge shaped blocks or voussoirs were placed side by side until the keystone was wedged between the two top adjoining blocks thus completing the semi-cirlce. The centering would then be removed since the arch, once completed, was self sufficient. Once the arch was built, the ends needed to be prevented from spreading. Roman or round-headed arches are generally self-supporting if they are fully semicircular, but segmental arches and the various mulit-centered arches need more support, thus the development of skewbacks and other structural ornaments.

Paris France

Art Nouveau Arch

The Art Nouveau period spanned from 1880 until 1920 all across Europe and North America. Excessive, eccentric, fanciful, the Art Nouveau arch is a compilation of swirls, flourishes and floral patterns, the insinuating tendrils of which adorn doorways, windows and most prominently the entrances to the then new means of transport, the metro or subway. When constructed of iron or steel, the Art Nouveau arch can be structural. When in stone, it is usually a surface decoration.

Bell Arch

A bell arch is a semicircular arch, often carved from one piece of stone, which rests on two rounded corbels resulting in a shape somewhat similar to a bell. - belfry in village north of Vevey. A bell arch can also be carved from one peice of stone to resemble a bell as in the example from Les Baux de Province.

The built arch spans a distance that would be impossible for just one member, so it is built up either with lamination or with reinforcing in steel, iron or some other material.

Byzantine Arch drawing

Multifoil Byzantine Arch

Byzantine arch

The Byzantine arch is destinguished by a central colonette or colonettes,without which it is not structural. The arch can be round headed, lancet or multifoil. Byzantine arches were developed in Turkey duing the 6th century and can be found in the Hagia Sophia. They were prominent during the Romanesque period , 800 to 1100, then gained prominence again during in Romanesque Revival and the late 19th century craze for all things exotic.

Camber Arch drawing

Camber Arch

Paris France

Camber Arch

In architecture a camber or camber arch is a very small, almost indecernable, arching or bowing of a joist, lintel, or other structural element to compensate for deflection due to loading. A Camber Arch is thus an arch that is, in fact, segmental but so slightly arched as to be almost imperceptable.

Catenary Arch drawing

Catenararian Arch

Amsterdam Netherlands

Catenarian Arch

Catenarian arches were exremeley rare in architecture prior to the 1960s and are still much more common in engineering, particularly bridges. A catenary curve, which makes up the arch, is the curve theoretically created by a flexible chain or chord hanging from two fixed points and acted upon by tha single source of gravity. y=kcosh (x) overk. In architectural applications the two fixed endpoints are generally at the same height making the catenary curve roughly like a U or a parabola. See also Parabolic Arch.

Discharging Arch

A discharging arch is built over a lintel in an opening and helps to deflect the load above to the piers on both sides, relieving the lintel of some of its load and thereby preventing fractures and dislocations. Discharging arches are used frequently in Roman and Neoclassical architecture, but they are often disguised by elaborate architraves and other finishes.

Flemish and Dutch architects accentuated the discharging arch by using dichromatic brick and stone, and by **** the lintel within the arch structure as shown in the early example from ghent from the 13th century.

Drop Arch

The drop arch has two centers and radii less than the span. If the radii and centers are equal to the span they are called equilateral arches. Lancet arches have two centers and radii less than half the span. The ??? has two radii and radii more than the span.

Flat Arch

A common term for a straight arch, used in Victorian designs, often in brick. The arch is made from vertical bricks or from stone voussoirs. can be one unit of stone. It is considered an arch because it transfers the load above onto the two abutments on the side.

Norman Arch

The Norman style was a variety of Romanesque and is characterized by simple, massive forms. the arch is generally plain and rounded at the top. Later in the period arches, doors and windows became more ornate, but they were always rounded. Geommetrically, this arch is the same as a round-headed arch. The difference is in the massive forms indicative of the time that it was built.

Geneva Switzerland

Ogee Three-Centered Arch

The ogee curve is created using by the union of a concave and a convex arch. The result looks a bit like an S. This is used at the top of arches as well as for the profile of mouldings. The ogee arch is Gothic in design. If the ogee curve has the convex or hollow part upwards it is referred to as Cyma Reversa or Cyma Rectas.

A rampant arch is an arch that has one impost higher than the other. These are usually pointed arches, and are often found on corners where hallways or arcades meet. They are also found on older structures that are built on sloping or terraced sites as is the case is Silvicane.
