Abstract
The so-called “baraccata house” – the first theorised building answer to earthquake-resistant behaviour improvement of the traditional masonry fabrics, as well as the first organic practical outfit of a legal post-seismic reconstruction standards (1784) – is attracting the increasing interest of a wide turnout of experts and scholars, because of its good performances in this field, as observed in well-conserved historic so-made examples and, more lately, in the laboratory testing activities on proper specimens (CNR-IVALSA). Focusing to Ischia’s historic tuff-masonry heritage, built in association with timber or metal frames after the massive 1883’s earthquake, this paper examines island last existing episodes, being fortunately survived replacements with reinforced concrete elements spreading during the 20th century. Thus, their constitution, layout and arrangements have been surveyed and assessed at the light of on-site stratigraphic and “as-found” conditions analyses of current fabrics, also helped by relating to proper original unreleased philological corpus. Therefore, so-made dwellings and architectures detailed account has been obtained, relevant to designing compatible building conservation treatments, as well as for to up-dating the specific frame solutions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
