6. Redundancy and Robustness Quantification of Bridge Systems based on Reliability and Risk Approaches
Sammanfattning : Over the last few decades, evaluating the performance of existing structures has become increasingly important, particularly as the number of bridges reaching their design life continues to rise. As a result, there is a growing need for effective and accurate procedures to guide the assessment of the current structures' capacity and safety levels to implement appropriate maintenance and rehabilitation strategies.

7. Reliability-based Assessment of Concrete Dam Stability
Sammanfattning : Risk management is increasingly used in dam safety and includes risk analysis, risk evaluation and risk reduction. Structural Reliability Analysis (SRA) is a probabilistic methodology that may be used in the risk assessment process. LÄS MER
8. Improving the Dynamic Design Philosophy of High-Speed Railway Bridges Using Reliability-Based Methods
Sammanfattning : Modern railway infrastructures, especially bridges, are exposed to significant vibrations with potential safety implications. In this context, previous studies have shown the inconsistency and inadequacy of some conventional design methods necessitaing them to be improved. The assessment of safety inherently deals with uncertainties. LÄS MER
9. Structural Reliability and Identification with Stochastic Simulation - Application to Railway Mechanics
Sammanfattning : System identification of structures based on measured response data can play a key role in improving reliability based structural designs. However, the experimental limitations of in situ tests and uncertainties of required model complexity together with the inverse nature of system identification give rise to a number of challenging issues.

10. Structural Safety Analysis of Bow-Doors
Sammanfattning : Bow-doors are one of the most vulnerable parts on a RoRo-vessel. At the same time, they are necessary for the profitability of todays RoRo-vessels.The minimum design rules for bow-door systems, stated in the International Association of Classification Societies (IACS) S8, constitute the basis for the class rules.
