ABSTRACT
During the two decades around the turn of the 20th century, a particular kind of vaulted roof became widespread: it had a metal structural work embedded in concrete and consisted of ribs and meshes of reinforcements strung between those ribs. This structural work was based on the criteria for metal vaulted roofs during the second half of the 19th century; it ensured the static equilibrium of large roofs and reduced construction time and costs by functioning simultaneously as a supporting framework for centering. Embedding it in concrete made this metal structural work a crucial point of reference during the 1920s in the production of the Dyckerhoff & Widmann company’s vaults.
