The Colosseum opens: arch and concrete at civic scale

node

The Flavian Amphitheatre is inaugurated in Rome. It is the arch and Roman concrete working together on a building rather than a bridge: an outer skin of arcaded travertine, radial and annular concrete vaults carrying the seating and the circulation, and a plan that can empty tens of thousands of people through arched exits. What it demonstrates is not span but organisation - the same structural unit repeated until it becomes a building type.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.

  39. Standard study of Roman concrete vaulting, its materials, aggregate selection and construction sequence, including the graded-aggregate practice used in large domes. Supports the MATERIAL_ROMAN_CONCRETE and SITE_PANTHEON records. V55 verification basis: real and standard, but not consulted in this session; no research domain was reachable.
