SUREBRIDGE project public kickoff meeting on 27th May 2016
SUREBridge project kick off and technical update
On 27th May 2016, the SUREBridge project held a public kick-off in Rotterdam, the Netherlands. The main aim of the event was to introduce the project and find potential stakeholders for the implementation of the results. Around 30 participants from the City of Rotterdam (as host of the event), city of Malmö, Dutch road administration and research institutes attended and the feedback was very positive.

Within the project, Work Package (WP) 3 is now developing the FRP deck concept for San Miniato bridge (the case study bridge in the project) and its connection to the existing concrete deck. The conceptual design of the deck is accomplished. To acquire a sustainable solution for connection between the Fiber-Reinforced Polymer (FRP) and concrete decks, we have worked out a solution to use steel fiber reinforced high performance mortar instead of epoxy bonding. The new solution will pose less impact on the environment and involves less health hazards. Prototyping of the pre-stressing device, for application of strengthening CFRP laminates, is accomplished and preliminary tests on large scale beams are scheduled in late August.
The overall strengthening design concept is being carried out in WP4 and the preliminary findings indicate that the SUREBridge solution offers the following advantages:
- Increased ultimate bending capacity of up to 50%
- Improved serviceability and durability due to application of Pre-stressed CFRP strengthening laminates (mainly due to reduction of crack width)
- Improved fatigue performance of reinforced concrete girders
