A regulatory document was issued by the National Research Council (CNR) of Italy on the use of FRP for strengthening structures: 'Instructions for Design, Execution and Control of Strengthening Interventions by Means of Fibre-reinforced Composites' (2004). Emphasis is also given to specific requirements for seismic applications. This document, described in more details in the paper, sets for the first time in Italy some standards for production, design and application of FRP for reinforced concrete and masonry constructions. It is also conceived with an informative and educational spirit, which is crucial for the dissemination, in the professional sphere, of the mechanical and technological knowledge needed for an aware and competent use of such materials. The document is the result of a remarkable joint effort of almost all professors and researchers involved in this emerging and promising field, from 15 universities, of the technical managers of major production and application companies, and of the representatives of public and private companies that use FRP for strengthening artifacts. Thus, the resulting FRP code naturally incorporates the experience and knowledge gained in ten years of studies, researches and applications of FRP in Italy.
