Final answer:
Arches superimposed on a wall have several purposes, including supporting the structure, creating openings, and adding strength to the wall.
Step-by-step explanation:
An arch is a series of arches superimposed on a wall. They have several purposes:
- Supporting the structure: The arches distribute the weight of the wall and other loads evenly, providing stability and strength to the overall structure.
- Creating openings: By using arches, larger openings can be created between the arches, allowing for more spacious areas and improved airflow.
- Adding strength to the wall: The construction of arches minimizes the shear load imposed on the wall, making it stronger and able to withstand more pressure.
