What it is Filled

An arch is a structure spanning a space in a vertical plane, typically with a curved profile, that may or may not support a load above it, in forms such as round, pointed, flat and diaphragm arches, built of stone, brick, wood or iron.

Why it exists Filled

Let an agent handle arches by form, material, structural behaviour, condition and heritage.

Distinguishing features Filled

  • Structural arches carry loads mainly in compression.
  • Structural arches require supports capable of resisting their thrust.
  • Arch forms help define architectural styles.
  • Freestanding arches can serve as monuments.

What robots and AI may and may not do Filled

Must not

  • Remove or cut into an arch or the walls that restrain it without a structural assessment.
  • Load an arch beyond what its owner or engineer has approved.
  • Damage historic arches or carved stonework.

Only with a human decision

  • Altering, repairing or demolishing an arch in an occupied or listed structure.

May

  • Inspect and report the condition of an arch, such as cracks or displaced stones.
  • Describe an arch and its form from drawings and records.

Moral aspects Filled

  • A failing arch can bring down what it supports onto people.
  • Historic arches carry the craft and identity of places.

Who is affected

  • Occupants and passers-by
  • Owners of the structure
  • Heritage communities

Owners Filled

Steward

The owner of the structure; heritage authorities protect listed arches.

Master systems

  • Heritage registers where listed

Recognition required Filled

  • Curved span with springings and keystone
  • Forms such as pointed or round
  • Materials from stone to iron
  • A curved span over an opening; triumphal arches and whalebone arches are freestanding forms.

Capabilities and actions required Filled

  • design and build it
  • assess its stability
  • repair and conserve it
  • identify its style

Hazards and failure modes required Filled

  • Collapse from abutment movement
  • Keystone or mortar failure
  • Vehicle strikes

Standards and interfaces required Filled

  • Masonry assessment codes
  • Heritage protection law

Context of use required Filled

  • Spanning openings and carrying loads in buildings and bridges, and as monuments.
  • round and segmental arches
  • pointed arches
  • flat arches
  • diaphragm arches
  • triumphal and memorial arches

Sources Filled

  1. Wikidata item Q12277: arch - identity and sense of the item
  2. Wikipedia: Arch - general description of the item

Open questions

  • Should arch forms be separate entries?
  • How should structural assessments be recorded?
  • How should freestanding arches be linked to monuments?
