Item Development and application of FASSTbridge solution to Jarama bridge (fast and effective solution for steel bridges lifetime extension)(International Association for Bridge and Structural Engineering (IABSE), 2018) Chataigner, Sylvain; Benzarti, Karim; Foret, Gilles; Caron, Jean François; Quiertant, Marc; Zalbide, Maria; Garcia, David; Calderon, Inigo; Pinero, Ignacio; Gemignani, Gianluca; Birtel, Veit; Lehmann, Frank; Wahbeh, Mazen; Boundouki, Rami; Martin, Elena; Sopena, Luis; Weidemueller, Mark; Fischer, Michael; Iborra, Concepcion; E&I SEGURAS Y RESILIENTES; Tecnalia Research & InnovationOne of the goals of sustainable development applied to bridge infrastructure is to provide bridge owners with strengthening solutions that may lead to an increase of existing structures service life. In the case of steel bridges, the assessment of the remaining service life is most often linked to the determination of the structural deterioration caused by corrosion and fatigue. Damage caused by fatigue is very difficult to assess before crack initiation, and is more bound to occur in old structures, for which the phenomenon was not taken into account in design before 1970. In addition, old steel materials present a more brittle behavior. In answer to these challenges, the FASSTbridge project, financed through European Infravation call, aimed at developing a pre-cracking fatigue assessment and strengthening methodology for steel bridges based on the technology of adhesively bonded composite. The proposed article presents some of the results of this project.Item Practical application of new simulation methods for the elimination of geometric instabilities in centerless grinding(2005) Lizarralde, R.; Barrenetxea, D.; Gallego, I.; Marquinez, J. I.; Bueno, R.; Tecnalia Research & InnovationElimination of geometric lobing in centerless grinding has been extensively investigated. Several models have been successfully developed, but no practical tool has been implemented on machines to ease the setting up of the machine to ensure stable conditions. This paper describes a software tool which has been developed for setting up and optimization of centerless plunge grinding processes to avoid geometric instabilities. The software generates stability maps showing the stable and non-stable geometric configurations and the number of lobes generated in non-stable conditions. Complementary time domain models quantitatively predict the evolution of the profile error for each geometric configuration.
