Abstract: The use of fiber reinforced polymer (FRP) laminates to strengthen and repair of steel beams has increased during the last decade and is tending to replace traditional methods, such as welding or bolting of additional steel plates. In this context, one of the issues, which require more research, is design of adhesive joints used to bond FRP laminates to steel substrates. This paper is mainly concerned with evaluation of damage mechanics-based approaches to predict the strength of adhesive joints used to bond FRP laminates to steel beams. Adhesively bonded CFRP/steel double-lap shear specimens are numerically modeled using cohesive zone modeling (CZM) and the results are compared with experiments. The input cohesive material data are obtained from three series of experiments. The results indicate that the proposed methodology to obtain fracture data results in good predictions using CZM. The prediction method presented in this paper could be used in practice to determine the strength of

Abstract: In Italy, unauthorized building is a very common phenomenon. In the present paper, we show the first results of a research focused on the impact of unauthorized buildings on urban and local systems, which frustrates the city plans and the previsions done before. For a start, it is appropriate to underline that if we want to know the amount and the quality of unauthorized building in the Italian Regions we need to proceed with a direct survey since Italian institutions, both at a national and at a local level, have not publicized any datum even if nearly thirty years have passed since the first national law concerning “building sanction” (Erbani, 2003). Italian laws determining rules and conditions in order to get building indemnity have been promulgated in 1985 (L. n. 47), in 1994 (L. n. 724), and in 2003 (L. n. 326). Because of the inefficient controls and of the increasing of unauthorized building, in the Eighties, Italian Government promulgated a law establishing that it was possibl
