Work Packages

WP1 Management: This WP is devoted to the financial, administrative and legal coordination of the project both within the FASSTbridge consortium and with the Infravation Secretariat in order to guarantee the right development of the project. Project scientific coordination and monitoring will be carried out too, in order to prepare proper reports to be submitted to the Infravation Secretariat.

WP2 Life-time expectancy for existing steel bridges: assessment methods and evaluation techniques: The aim of WP2 is to define a methodology for assessing the fatigue remaining life, designing the strengthening interventions and tackling maintenance. Tools, analysis methods and techniques to detect possible fatigue problems that visual inspections may not identify will be defined. The idea is to create a preventive, reliable, easy-to-apply method to foresee fatigue-derived issues and recalculate life-time expectancy. Moreover, the method for designing and applying the strengthening interventions is also defined at this WP. Finally, innovative monitoring strategies to control performance and contribute to databases for probabilistic assessment methods are defined as part of the maintenance phase. 

WP3 Development and selection of the strengthening components and first prototyping: This part of the project will be developed in tandem with WP2 and is focused on the definition of the materials that will be used in the strengthening process. CFRP strips are well known, and thus, the research efforts will focus on the adhesive. There are two main issues, connected between them, related to the use of adhesives in externally bonded strengthening materials: non-desired premature debonding failure mode and lack of durability of the material in aggressive environments. For this reason an adhesive will be designed to improve these drawbacks and guarantee an optimum performance and durability of the strengthening system. The resulting adhesive will be characterized to analyse its rheological behaviour and durability and to suit current requirements and standards.

WP4 Strengthening system process qualification: The adopted components will be validated within the work developed in this WP. The adhesive possibilities will be assessed through the execution of tests that simulate the real and accidental situations the material may have to overcome during its operational life. Destructive, non-destructive as well as monitoring technologies will be adapted and used for this purpose.

Once the previous validation is complete, all the FASSTbridge methodology will be summarized in a guideline: bridge assessment, design of the strengthening solution and its application and correct maintenance. In parallel, the pre-certification process for the strengthening system will be properly defined. Moreover, the parameters to conduct an accurate cost-benefit analysis and draft LCA of the intervention will be defined.

WP5 Real case demonstration of the solution: At this point of the project the whole solution proposed will be tested by means of a demonstration in a real composite bridge at Madrid (Spain) specially selected for this project. The intervention will be designed according to the project line and checked in a monitored load test under real conditions.

The test results will help to establish a series of technical, environmental and economical conclusions, comparing FASSTBRIDGE to standard repair solutions so real technical, LCA and cost-benefit analysis can be made. In addition, the gained experience can be used to refine the guideline elaborated in the previous WP.

WP6 Dissemination, Communication and Exploitation: The main objective of WP6 is to maximize the impact of the FASSTbridge results by means of exploitation, analysing the potential use of the developed solution and the commercialization of the industrial product elaborated within the FASSTbridge project. Moreover, communication and dissemination of information will be carried out through two different ways. Firstly, with academic dissemination, the aim is to spread the acquired knowledge throughout the academic community. Secondly, with industrial/technical dissemination the aim is to communicate the project and promote project results to different target groups: professionals, stakeholders, authorities and general public.
