  • This report is part of the Infravation research project “Fast and effective solution for steel bridges life-time extension”. Within working package 2 “Life-time expectancy for existing steel bridges: assessment methods and evaluation techniques”, this report is part of the second delivery, Work Package 2.2, for the definition of design, application and maintenance of the strengthening system and definition of innovative monitoring strategies. This report will first revise the existing literature and state-of-art of strengthening steel structures with CFRP-laminates to distinguish FASSTbridge approach from existing research. On several sample applications from all over Europe and the USA, the successful use of CFRP on steel bridges is documented. Typical fatigue-prone details are discussed and explained, to detect parts of a structure before fatigue damage occurs. In several examples different kind of attachment of CFRP-laminates and their strengthening output are evaluated with regard to the strengthening approach suitable for FASSTbridge. Doing this, the three-step-path of Diagnosis, Safety Evaluation and Design of Intervention is explained and provides a basis for the developed methodology. Dealing with the intervention strategy and maintenance, protocols are developed based on existing standards and procedures to achieve fast and quality interventions to apply the strengthening and to ensure swift and effective interventions. Monitoring strategies are established and to be applied in the strengthening intervention with two complementary options: Quality control as short time monitoring for early evaluation and Maintenance as a continuous monitoring to control the fatigue damage on site. These options will provide data for its use in probabilistic assessment methods. The Monitoring Application techniques will be defined and then specified and fine-tuned in WP 4 before their demonstration in WP5.

Within Work Package 4 “Strengthening system process qualification”, the adopted strengthening system for Jarama Bridge in Madrid, Spain, is to be validated by means of a well-defined experimental campaign regarding static, dynamic, application and durability topics of the assembly. This report covers the result of task 4.6 “Fine-tuning and formulation of the methodology: assessment, design, application and maintenance guideline”. In the scope of Work Package 4 it is the fourth delivery. This report seeks to fine-tune the methodology with inputs of Work Package 2 and the tasks 4.1 to 4.4. Doing this, a guideline will be developed, explaining the proposed methodology. This guideline will be simple and user friendly in order to reach a considerable amount of users.
  • This report is part of the Infravation research project FASSTbridge “Fast and effective solution for steel bridges life-time extension”. The document is related to Task 5.1 Design of the intervention: current bridge condition, bridge life-time recalculation and strengthening action within WP5 Real case demonstration of the solution. The report is dedicated to the description, analysis and evaluation of the current status of the bridge where the demonstration activities will be performed. This report is composed of four distinct parts: • The first part is dedicated to introduce the location of the bridge. • The second part is focused on the description of the bridge, describing its accesses and its different parts. • The third part analyse the original project dated in 1962 to understand how the bridge was designed and constructed. • The last part includes the information related to the detailed inspection carried out in the bridge including visual inspection, analysis of welded joints, paint analysis and tests and material characterization tests.
  • The project FASSTbridge will develop and demonstrate a reliable preventive, costeffective and sustainable solution for steel bridges life-time extension at a prefailure fatigue scenario. One of the main goals of the project is to achieve market and academic awareness of the project activities and results, and pave the way for market uptake and prompt exploitation of the FASSTbridge solution and its components. This deliverable (D6.1) presents the project media used for this project, namely, the project website, project logo, project leaflet, and Infravation newsletter.
  • This report is part of the Infravation research project “Fast and effective solution for steel bridges life-time extension”. Within Work Package 5 “Real case demonstration of the methodology”, the adopted strengthening system for Jarama Bridge in Madrid, Spain, is to be validated by means of a well-defined experimental campaign regarding static, dynamic, application and durability topics of the assembly. This Deliverable uses the results from WP2 and WP4 to assess the condition of the existing bridge and to determine its remaining service lifetime. Then, the extended service life according to given repair and strengthening actions is calculated. Repair and maintenance costs will be accounted for in each of the proposed actions. The most suitable option from this analysis will be selected for implementation in the Implementation of FASSTbridge strengthening system in the Jarama Bridge.

This Deliverable 5.5 links directly to D4.2, D4.4, D5.3 and D5.5: • D4.2 FASSTbridge strengthening system verification report, which, amongst others, researches the influence of the insertion of the delamination sensor. • D4.4 FASSTbridge methodology, which in parts describes the monitoring strategy and the concept of the delamination sensor. • D5.3 Implementation of FASSTbridge strengthening system in Jarama Bridge: describes the strengthening process carried out on site in the Jarama Bridge. • D5.5 FASSTbridge technical, environmental and cost benefit report – Study case, which shows the analysis of the data collected on site. A strengthening system with adhesively bonded CFRP reinforcement was developed in the Infravation project FASSTbridge to extend the remaining fatigue lifetime of existing steel bridge constructions. On-site loading tests were carried out to verify the system’s effectiveness. Furthermore, the premature debonding of CFRP and steel is seen as a major risk to lose the contribution of the retrofitting system. Consequently, an ultrathin debonding sensor was developed and integrated in the adhesive layer between steel and CFRP as part of the strengthening system. It is suited for continuous monitoring of the integrity of the adhesive joint. The deliverable collects the data form the on-site testing and explains the underlying physical principles of the debonding sensor. It gives insight into the performed tests for the calibration and verification of its functionality.
