In the way of thinking about urban morphology as a scalar product of the factors that influence each other, in particular building typology, local structure, overall structure and territory, and that contribute together to generate an organism, it is therefore possible to read this part of the historical center as the last product, but not definitive, of a "process". The reading method on the consolidated structure, later renovated in a post-unification era, is based on the analysis of the most abundant building typology and on the permanence and derivations of local typological processes that led to the formulation of the “line house” in nineteenth-century line, the predominant building type of roman expansion in nineteenth-twentieth century. The reading of the restructuring, understood as synchronic action on the historical center, has been implemented instead by the analysis of synchronic variations at “line house” through the research of all projects registered for the edification of each block. Thus we can see how the blocks resulting from the transformation, in the logic of a restructuring "contromaglia" like the one for the opening of Viale Trastevere, will be the result of the disconnection of the existing blocks in which the building type adopted has had to adapt to a lower return situations: a reading of a synchronic action on a diachronic process that gives us the modern morphological apparatus.

A method for structural health monitoring of cable-stayed bridges based on the dynamic distributed sensing of bridge deck strains is introduced in this article. The objective is to detect the location and the magnitude of the cables that have totally or partially lost their tensile load-carrying capacities. Dynamic sensing provides a realistic approach for condition assessment of the bridge under operational conditions. A Brillouin scattering optical time domain analysis (BOTDA) fiber-optic sensor was used to monitor the distributed strain in the deck of a scaled model cable-stayed bridge in the laboratory. The formulations developed in the present study take advantage of the dynamic distributed sensing capability of the BOTDA in amplitude transfer (AT) mode for the establishment of a relationship between the redistribution of deck strains and the tension loss in the individual cables of cable-stayed bridges. The experimental program involved single cable and multicable damage scenarios. The appli...
