SUSTAINABLE BRIDGES PROJECT Masonry Arch Bridges Subgroup
Sustainable Bridges Project • • • Objectives Members Work packages WP 2: Survey WP 3 -5: Condition Assessment, Monitoring WP 4: Loads, Capacity WP 6: Repair and strengthening WP 7 -8: Demonstration, bridge tests WP 9: Dissemination
Objectives • Increase the transport capacity of existing bridges by allowing axle loads up to 33 tons for freight traffic with moderate speeds • Increase the residual lifetime of existing bridges with up to 25 % • Increase the capacity for passenger traffic with low axle loads by increasing the maximum speeds to up to 350 km/hour • Enhance strengthening and repair systems
Members • • • Czech Republic Denmark Finland France Germany Norway Poland Portugal Spain Sweden Switzerland United Kingdom
Work packages WP 1 Start up and Classification WP 2 Guidance and Review WP 3 Condition Assessment, Inspection WP 7 Demonstration, Field testing on old bridges WP 4 Load, Capacity and Resistance WP 6 Repair and Strengthening WP 9 Training and Dissemination WP 5 Monitoring WP 8 Demonstration, Monitoring on New Bridges
WP 2 Survey • 40% of all European bridges is masonry • 60% of masonry bridges are over 100 years old
WP 3 -5 Condition Assessment, Monitoring University of Salford Acoustic Emssion Technique
Toolbox (example)
WP 4 Loads, Capacity 1. Long-term effect of traffic loading on masonry arches: • Fatigue limits • Critical modes of failure • Effect of deteriorated masonry. 2. Soil-structure interaction. 3. Modelling deteriorated masonry. 4. Probabilistic assessment methods.
WP 6 Repair and strengthening FRP reinforcement + Radial pinning Steel studs Glass fibre sheet
WP 7 -8 Demonstration, bridge tests
