What is Arch and Arc in Construction – Application of Arch
What is an Arc?
A circle’s arc is referred to as a portion or section of its circumference. A chord of a circle is a straight line that might be created by joining the arc’s two ends. A semicircular arc is one whose length is exactly half that of a circle.
Symbol of Arc
The arc is represented by the letters ‘⌒’ or ‘⌢’ Euclidean geometry. Since the sequence of the points is irrelevant, the arc in the previous illustration is referred to as arc AB or BA. The letter AB with a curved line above it can be used to represent this, as in as 
What is an Arch?
The weight above it or, in the case of a horizontal arch, such as an arch dam, the hydrostatic pressure against it may or may not be supported by an arch, which is a vertically curved structure that spans an elevated space. Although vaults and arches are often used interchangeably, a vault can be identified as a continuous arch forming a ceiling.

Uses of Arch in construction
It is not common for Arch to be used in the construction industry. Arch is a type of structural element that is used in architecture and engineering to support loads and spans over openings or other elements. Arches are typically made of brick, stone, or concrete, and they are used to create openings or passageways, such as doors, windows, and bridges.
In construction, arches are typically used as a structural element in buildings, bridges, and other structures. They are particularly useful in situations where it is necessary to span a large distance without using columns or other vertical supports. Arches are able to support large loads and transmit them to the ground through their shape and the way they distribute weight.
It is possible that the term “Arch” could be used to refer to other applications of the arch shape in construction, such as the use of arched openings or arched roof trusses. However, it is more likely that the term “arch” would be used to refer specifically to a structural element that is used to support loads and spans over openings or other elements.
Advantages of Arch in construction
Arches are a common structural element in construction and have several advantages that make them useful in various types of buildings and structures. Some of the main advantages of using arches in construction include:
Strength and stability: Arches are able to distribute weight evenly, which makes them very stable and able to withstand heavy loads. This makes them particularly useful in construction projects where there is a need for large, open spaces or where the structure will be subjected to heavy loads, such as bridges and tunnels.
Versatility: Arches can be used in a variety of contexts, including in walls, ceilings, and floors. They can also be used to span large distances and can be adapted to fit different shapes and sizes.
Aesthetics: Arches have a graceful, elegant appearance that can add visual interest to a building or structure.
Efficient use of materials: Because arches are able to distribute weight evenly, they can often be constructed using less material than other types of structural elements, such as beams or columns. This can make them more cost-effective and efficient to use.
Durability: Arches are known for their longevity and ability to withstand the passage of time. Many ancient structures featuring arches, such as the Roman aqueducts and the Pantheon in Rome, are still standing today.
