Archbased

Archbased is a term used to describe an architectural design approach in which arches are the central organizing element of both structure and form. The concept emphasizes the arch’s ability to carry loads through compression, allowing for longer spans, fewer vertical supports, and a continuous, curvilinear spatial language. Proponents envision archbased design as a bridge between traditional masonry techniques and contemporary material capabilities, combining the aesthetic qualities of arches with modern performance requirements.

In practice, archbased design prioritizes clear load paths, with arches, vaults, and their voussoirs as primary structural components. The form often features repeating curvature, voussoir geometry, and keystones or imposts that articulate rhythm and stability. Materials range from traditional brick and stone to reinforced concrete, steel, and engineered timber, including precast arch segments and segmented vaults that simplify construction while preserving arch action.

Applications of archbased design appear in cultural centers, pavilions, pedestrian bridges, and restoration projects where the visual language of arches is valued alongside contemporary performance criteria such as seismic resilience, daylighting, and acoustics. The approach can enable large, column-free interiors and graceful exterior silhouettes.

Critics note that archbased projects may involve complex detailing at joints and compression transitions, potential costs associated with curved forms, and the need for precise fabrication and assembly. When well executed, archbased design can yield durable, aesthetically cohesive spaces that reference architectural heritage while leveraging modern materials and techniques.
