1. Machine Learning – Based Dynamic Response Prediction of High – Speed Railway Bridges
University essay from KTH/Bro- och stålbyggnadAbstract : Targeting heavier freights and transporting passengers with higher speeds became the strategic railway development during the past decades significantly increasing interests on railway networks. Among different components of a railway network, bridges constitute a major portion imposing considerable construction and maintenance costs. READ MORE

2. Dynamic Design of Bridges on High-Speed Railway Lines
University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/ByggnadsmekanikAbstract : In recent years, high-speed railway has been on the upswing in the public debate, as Swedish authorities have affirmed the plans of a high-speed corridor connecting Stockholm, Gothenburg and Malm¨o. The track speed limit is not fully determined, but will be in the range of 250-320 km/h. READ MORE

3. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study
University essay from KTH/Bro- och stålbyggnadAbstract : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.

4. Train Induced Vibration Analysis of an End-frame Bridge : Numerical Analysis on Sidensjövägen
University essay from KTH/Bro- och stålbyggnadAbstract : Higher speeds and higher capacity will cause the Swedish rail network to be exposed to disturbing dynamic effects. Higher speeds cause higher vertical acceleration levels of the bridge deck. In this thesis, a numerical analysis of a three span end-frame bridge subjected to train induced vibrations is performed.

5. Structural Health Monitoring of Bridges using Machine Learning : The influence of Temperature on the health prediction
University essay from KTH/Bro- och stålbyggnadAbstract : A method that uses machine learning to detect and localize damage in railway bridges under various environmental conditions is proposed and validated in this work. The developed algorithm uses vertical and lateral deck accelerations as damage- sensitive features. READ MORE
