This test was required to integrate the final load test in view of the importance of the viaduct and because of its structural typology that implies a particular and quite complex dynamic behavior. The structural control is performed by comparing modal parameters obtained experimentally with those predicted by the design structural model, and represents the first step of a future structural health monitoring program that foresees tests performed every two years. The Caffaro Viaduct is a part of the project for modernization and retrofit of the A3 highway (Salerno-Reggio Calabria), near Lauria in south Italy. The longitudinal development of the viaduct is about 400 m; it is formed by two separate steel-concrete composite decks, 12.7 m wide, supported each one by two steel trestles that are connected nearly the top by transverse steel truss beams. The overall dynamic response of the structure is checked by means of three different sensor placements with the aim to highlight three different behaviors: i) the global behavior of both carriageways, ii) the flexural-torsional behavior and iii) the transverse one of the southbound carriageway. The data collected during ambient vibration tests are processed with Stochastic Subspace Identification Covariance Driven in order to estimate the modal parameters. Natural frequencies and mode shapes experimentally determined are compared with the numerical ones obtained with the predictive finite element model developed for design purposes and then with the model slightly modified to account for the real operating conditions of the viaduct, in terms of both stiffness and masses. A refined model updating is in progress to fix a benchmark, necessary for the scheduled structural health monitoring program.","PeriodicalId":262720,"journal":{"name":"2016 IEEE Workshop on Environmental, Energy, and Structural Monitoring Systems (EESMS)","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131668003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, repetition intervals of radar instruments are in the order of several days for routine operations, reaching daily or higher frequencies only in tasked conditions. Therefore, to follow flood dynamics, images acquired by different sensors at different times may be beneficial. In the present work, multi-temporal SAR intensity, InSAR coherence and optical data are considered to describe a flood event occurred in the Basilicata region (southern Italy) on December 2013. In this case study, optical data have a twofold role: they allow to follow the flood dynamics (because SAR and optical data have been acquired in different dates during the inundation event), and they add information concerning the land cover of the analyzed area. The data fusion approach is based on Bayesian Networks (BNs). It is shown that the synergetic use of different information layers can help detect more precisely the areas affected by the flood, reducing false alarms and missed identifications which may affect algorithms based on data from a single source. The produced flood maps are compared to reference maps, independently obtained; the comparison indicates that the proposed methodology is able to reliably follow the temporal evolution of the phenomenon, assigning high probability to areas most likely to be flooded, reaching accuracies of up to 89%.","PeriodicalId":262720,"journal":{"name":"2016 IEEE Workshop on Environmental, Energy, and Structural Monitoring Systems (EESMS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127789661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
