PRESTRESSED CONCRETE BRIDGES
Condition Assessment and Future Challenges
This report provides an extensive review on current situation with prestressed concrete bridges based on deep knowledge of engineering and science. The behaviour in ultimate and serviceability limit states and the level of safety, reliability, and robustness are studied. Repair and Strengthening methods are reviewed and Needs for Maintenance Strategies are outlined.
Finally, it is demonstrated on examples that any compromises in design and construction, neglecting proper maintenance and in particular overlooking inspections to identify in early stage potential failures could have a disastrous consequence with fatalities and finally resulting in multiplication of initial costs.
INNOTRACK Concluding Technical Report
The major stakeholders in the rail sector – infrastructure managers, railway supply industry and research bodies have proved jointly their potential to deliver highly innovative solutions for further developing a cost effective high performance track infrastructure towards significant reduction of both investments and maintenance related infrastructure costs. The proposed methodologies and tools had a strong influence on the reduction of rail infrastructure life cycle cost (LCC). The project has been founded by the EC commission under the 6th Framework Programme under the leadership of the International Union of Railways (UIC).
C4R (Capacity for Rail) Upgrading of infrastructure in order to meet new operation and market demands
This is one of the valuable deliverables of EU C4R project – Capacity for Rail addressing the needs for upgrading railway infrastructure to be capable of accommodating the increased volume of freight traffic expected from modal shift from road to railways. The released capacity of existing networks due to moving the great part of long-distance passenger traffic to the new high-speed lines could be allocated for freight traffic. However, the current infrastructure dated from last century shall be upgraded and modernised to meet new operation models and demands to enable the railway operators to offer the competitive services to road haulers. All these important aspects of upgrading the existing lines are dealt with in this report released for publication.
