Arches are architectural structures that rely on the placement of carefully arranged stones to support weight and distribute stress. The stones are typically arranged in a specific pattern to help maintain the structure's stability and durability. One of the key characteristics of arches is the placement of stratified stones in a radial pattern.

Radial Placement of Stratified Stones
- The term "stratified stones" refers to stones that have been cut or shaped to fit together in a particular pattern.
- In an arch, these stones are typically placed in a radial pattern, meaning that they fan out from the center of the arch.
- This pattern helps to evenly distribute weight and stress across the entire structure, which is important for maintaining stability and preventing collapse.
- The stones are often arranged in a series of concentric rings, with each ring made up of stones that are slightly smaller than the ones below it.

Benefits of Radial Placement
- One of the main benefits of placing stratified stones in a radial pattern is that it helps to distribute weight and stress evenly across the arch.
- This can help to prevent the arch from collapsing or sagging under the weight of the structure above it.
- Additionally, the radial pattern can help to create a more visually appealing structure, as the stones are arranged in a symmetrical pattern that draws the eye inward toward the center of the arch.

Conclusion
Overall, the radial placement of stratified stones is an important feature of arches, helping to ensure their stability and durability over time. This pattern of stone placement is carefully designed to evenly distribute weight and stress, while also creating a visually appealing structure.
