Basic Structural Concept of Arches
The basic structural concept of arches involves the transfer of weight from the horizontal surface above to the supporting sides, or abutments. This design efficiently directs compressive forces downward and outward, enabling the arch to support substantial loads.
The keystone, placed at the apex of the arch, locks the other voussoirs (wedge-shaped stones) into position, providing stability. This central element is critical as it distributes the forces evenly, preventing the stones from collapsing inward.
In ancient construction, the materials used for arches—such as stone or clay brick—were chosen for their compressive strength. The precise shaping of each voussoir was essential for ensuring tight interlocking, which enhanced the structural integrity.
The development of the arch marked a significant evolution from corbeling, enabling the creation of larger, more durable openings. Its fundamental principle relies on compression, making it a reliable technique in both historic and contemporary architecture.
Types of Ancient Arches
Ancient architecture employed various types of arches, each serving distinct structural and aesthetic purposes. These arches evolved across different cultures and regions, reflecting available materials and technological knowledge.
