The Modern Arch Has Classical Design Elements Yet Is Lightweight and Decorative

Arches have long been used in building design and in modern times they add a classical, elegant finish to a house build.  Originally built in materials such as stone, marble then cement, the easiest and most effective method to build an arch these days is to use a lightweight house moulding with a steel support.

Dating back to 3000BC was the original arch, the corbel arch consisting of two opposing sets of overlapping corbels, resembling inverted staircases, which meet at a peak and create a structure strong enough to support weight from above. Babylonian architecture made wide use of corbel arches. Then the Romans created a semicircular arch that could support great amounts of weight.  A wooden arch shaped frame was first constructed with stone work being built up around the frame and finally a keystone was set in position. This allowed the wooden frame to be removed and the arch was left in position. Stone arch technology was used on large buildings such as the Colosseum in Rome.

The next major design innovation in arches was in Gothic architecture with the experimental use of pointed arches. The pointed shape introduced a new aesthetic dimension and reduced the arch thrusts by as much as fifty percent which meant that the weight of the roof was now being supported by the arches rather than the walls and therefore the walls could be thinner.

The basket arch is a three-centred arch and sometimes called  ‘basket-handle arch’ or ‘anse de panier’. The Basket arch is a flattened arch whose ellipse like shape is determined by three arcs that are interconnected; with each radius being drawn from a different centre. Also known as Semi elliptical or Elliptical, this style of arch is mainly used in modern day building due to its simple design.
