Entity and identity of metal additions in ancient buildings

Abstract

The research investigates the role of steel in pre-existence, at first confined to consolidation, later extended to reuse. The metal artificial nature and the untraditional constructive system make more complex the issue of addition visibility in pre-existence, employed for static purposes or functional aims. Anyway, the iron entity is expressed each time in a specific way, which is compatible to the historic building, concealed among the masses involved, or highlighted in its essentiality.
