A segmental arch is a curved structure that forms less than a half-circle. Imagine a smile – that's a segmental arch. It's used in construction to span openings like doorways or windows, providing support and distributing weight. Compared to a full arch, it has a more shallow curve. It's like a flattened arch, requiring less vertical space. It's often chosen for its aesthetic appeal and efficient use of materials. Think of it as a compromise between a straight beam and a full arch.
