Safety and Probabilistic Modelling : Sustainable Bridges Background document D4.4
- 2007
-
Rapport (refereegranskat)abstract
- The main objective of this background document is to bridge the gap between the most advanced structural assessment techniques based on probabilistic methods and the daily practice of bridge evaluators in the railway agencies, not specifically trained on them and responsible of the load and resistance assessments. To this end, the background document explains and summarizes the basis of the safety assessment using a probabilistic approach, providing simplified methods whenever possible and also providing examples of application in order to make the documents more readable and understandable.The present background document is divided in the following deliverables:D4.4.1 Safety format and required safety levelsD4.4.2 Probabilistic modellingD4.4.3 Probabilistic non-linear analysisD4.4.4 Examination of fatigue safety and remaining fatigue life of structural details andcomponents in steel of railway bridges using probabilistic methodsD4.4.5 Long-term behaviour of subsoil below railway embankments – A simplified predictionmethod of settlements with a probabilistic approach

-
Tidskriftsartikel (refereegranskat)abstract
- The paper summarises the work on concrete bridges performed in the EU project Sustainable Bridges. The work provides enhanced assessment methods that are able to prove higher load-carrying capacities and longer fatigue lives for existing concrete railway bridges, and is implemented in a Guideline [1]. Methods for determination of in-situ material properties and advanced methods for structural analysis were developed. One main focus was non-linear analysis, since these provides the greatest potential for discovering of additional sources for load-carrying capacity. Furthermore, methods to assess the remaining structural resistance of deteriorated concrete bridges with respect to corrosion and fatigue were developed.

Konferensbidrag (refereegranskat)abstract
- The work presented provides enhanced assessment methods that are able to prove higher load-carrying capacities and longer fatigue lives for existing concrete railway bridges. It was performed as a part of the EU-project Sustainable Bridges. The results are implemented in the Guideline for Load and Resistance Assessment of existing European Railway Bridges, see SB-LRA (2007) and are reported in detail in a background document, see SB4.5 (2007). The work presents improved methods for the determination of in-situ material properties, for deterministic as well as probabilistic assessments. Advanced methods for structural analysis are presented, e.g. regarding combined shear, torsion and bending interaction. Recommendations are given regarding redistribution of sectional moments and forces obtained from linear finite element analysis. One main objective was to facilitate the use of non-linear analysis for structural assessment. This provides the greatest potential to discover any additional sources for load-carrying capacity, and gives a better understanding of the structural response. Another main objective was to provide methods to assess the remaining structural resistance of deteriorated concrete bridges. Recommendations are given on the effect of corrosion and a methodology is presented for assessment of remaining fatigue life, with emphasis on short-span bridges and secondary elements.

Konferensbidrag (refereegranskat)abstract
- The aim of the work presented here was to provide enhanced assessment methods that are able to prove higher load carrying capacities and longer service lives for existing concrete railway bridges. One main objective was to develop methods for non-linear analysis since this provides the greatest potential to discover any additional sources for load carrying capacity, and gives an improved understanding of the structural response. Another main objective was to provide methods for assessing deteriorated concrete bridge. Recommendations are given regarding the effect of reinforcement corrosion, particularly on anchorage capacity. Furthermore, a methodology for improved assessment of the remaining fatigue life of short-span concrete bridges and secondary elements is presented. Other topics treated are evaluation of material properties, simplified methods for structural analysis and the bending-shear-torsion interaction.
