Segmentbogengewölbe

Segmentbogengewölbe, also known as a segmental arch vault, is a type of vaulting in architecture. It is formed by the rotation of a segment of a circle around an axis. This differs from a typical barrel vault, which is formed by a full semicircle. The segmental arch vault is characterized by its shallower profile compared to a semicircular vault. This characteristic allows for certain structural and aesthetic advantages in building design.

The construction of a segmentbogengewölbe typically involves the use of voussoirs, or wedge-shaped stones, that are arranged in a curved pattern. The apex of the vault is flatter, and the springing points are wider apart than in a full semicircular vault of the same span. This geometry can distribute the load differently, potentially requiring less lateral thrust at the base. Historically, segmentbogengewölbe have been employed in various architectural periods and contexts, often chosen for their ability to span spaces with height restrictions or where a less pronounced curve was desired. Its appearance can be seen in bridges, underground structures, and certain roof constructions. The engineering principles behind its stability are similar to other arch and vault systems, relying on the compression of the materials to maintain its form.
