Archshaped

Arch-shaped is an adjective used to describe objects or forms that have the curvature of an arch. In geometry, an arch can refer to a curved segment of a circle or ellipse; in architecture, an arch is a structural element spanning an opening and bearing loads primarily by compression. When an element is described as arch-shaped, it exhibits a curved top that resembles the profile of an arch, though it may not function as a true arch structurally.

Applications in architecture and design: Arch-shaped openings appear in windows, doorways, bridges, and vaults. Architectural arches differ in profile: semicircular (Roman), segmental, pointed (Gothic), and horseshoe arches, among others.

Structural and aesthetic properties: Arch-shaped forms distribute weight to supporting elements, enabling wider openings with less material; keystone and voussoirs are typical features of true arches; arch-shaped motifs are common in decorative elements and logos.

Etymology and cross-cultural use: The term derives from arch, from Latin arcus; arch-shaped motifs are found across many architectural traditions, including Roman, Gothic, Islamic, and modern vernacular architecture.
