16. Numerical analysis and model updating of a steel-concrete composite bridge : Parametric study & Statistical evaluation
University essay from KTH/Bro- och stålbyggnadAbstract : In the year 2006, only 10 years after the steel- concrete composite bridge, Vårby bridge was built, fatigue cracks were found during an inspection. To further investigate the reasons and the potential danger of the cracks, an investigation under the commission of the Swedish Transport Administration was issued in 2009. READ MORE

17. Fatigue and dynamics of secondary beams in steel railway bridges
University essay from KTH/Bro- och stålbyggnadAbstract : Many steel railway bridges in Europe are older than 50 years whilethey are subjected to higher loads than they were originally designedfor. As many of these bridges are approaching the end of their designlife it is crucial to carry out accurate fatigue assessments in order toensure their safety and keep them in service. READ MORE

18. Soil Steel Composite Bridges for High-Speed Railways : 2D FEM analysis of the Björnbo Bridge
University essay from KTH/Bro- och stålbyggnadAbstract : This research aims to analyse the dynamic behaviour of Soil-Steel Composite Bridges when subjected by high-speed trains. the analyses of the dynamic response for these structures are needed since there is little research performed in the present field of knowledge.

19. Load Effect Modelling in Fatigue Design of Composite Bridges : An assessment of Fatigue Load Models 3, 4 and 5 according to SS-EN-1991-2 Actions on Structures – Part 2: Traffic loads on Bridges
University essay from KTH/StålbyggnadAbstract : At the turn of 2010/2011, Sweden went from designing structures according to nationaldesign codes to the new European standards Eurocode. For bridge engineers, this implieda change from a combination of BRO 2004 and BSK 07 to the Eurocode as the maindocuments, complemented by national documents such as TRVK Bro 11. READ MORE

20. Modal Testing and Structural Identification
University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/ByggnadsmekanikAbstract : Bridges have been built around the world for at least 3000 years and have made it possible for man to travel over obstacles like valleys and rivers, which has contributed to the rapidly growing infrastructure we have today. Efforts made to save materials and reduce production costs have led to lighter and slender structures, which in turn can cause dynamic problems where the bridge is sensitive to vibrations. READ MORE
