BRIDGE ARCH Meaning and
Definition
-
Bridge arch refers to a prominent architectural element used in the construction of bridges. It is a curved structural support composed of wedge-shaped stones or bricks that are arranged in a semi-circular or parabolic form. The arch shape distributes the weight placed upon it in a downward and outward manner, allowing it to effectively withstand compressive forces.
Typically built using masonry materials such as stone, brick, or concrete, the bridge arch is characterized by its ability to span a gap or opening, creating a stable passageway for vehicles, pedestrians, or water flow. The stones or bricks are carefully placed and bonded together using mortar, forming a strong and cohesive structure. The shape of the arch is crucial for its stability, as it evenly dissipates the forces acting upon itself, transferring the load from the upper portions of the arch to the supportive abutments or piers on either end. As a result, bridge arches are known for their durability and longevity, having been utilized in various historical and modern constructions around the world.
Bridge arches offer several advantages, including their aesthetic appeal, structural strength, and versatility in accommodating different spans and loads. They have been employed in diverse bridge types, such as stone arch bridges, viaducts, and aqueducts, as well as modern reinforced concrete or steel arch bridges. By incorporating bridge arches into their designs, engineers and architects can create visually stunning structures that effectively overcome geographical barriers, supporting the continuous movement of people, vehicles, and resources.
Etymology of BRIDGE ARCH
The etymology of the word "bridge" can be traced back to Old English, where it was spelled as "bryċġ" or "brycg". The term itself has Germanic origins and is closely related to the Old Norse word "brú", the Old High German word "brug", and the Gothic word "brugga".
The word "arch" comes from the Latin term "arcus", which means "a curved structure". It was used in the context of architecture to refer to a structure with a curved or semicircular shape. The Latin term "arcus" itself has Indo-European roots and can be connected to similar words in various ancient languages, such as Greek "arkhos" and Sanskrit "arka".
