1. 6. Dynamic Analysis of Portal Frame Railway Bridges - Case Studies Investigating the Structural Response

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

   Author : Benjamin Berg; Pontus Nyberg; [2020]
   Keywords : Dynamic Analysis; Portal Frame Bridges; High Speed Trains; Railway Bridges; Finite Element; Resonance; Modal Analysis; BRIGADE Plus; Technology and Engineering;

   Abstract : As the world continues to see an increase in carbon dioxide emissions, actions aiming towards reducing man's negative impact on the environment are paramount. To be able to compete with the air travel industry, the Swedish Transport Administration suggests a vast expansion of the existing railway system. READ MORE

3. 7. Dynamic Design of Bridges on High-Speed Railway Lines

   University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

   Author : Felicia Nilsson; Filippa Dahl; [2019]
   Keywords : High-speed railway bridges; bridge-train resonance; structural dynamics; modal dynamics; time stepping; soil-structure interaction; finite element method; BRIGADE Plus; Technology and Engineering;

   Abstract : 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

4. 8. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

   University essay from KTH/Bro- och stålbyggnad

   Author : Turgay Dagdelen; Shaho Ruhani; [2018]
   Keywords : Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

   Abstract : 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.

5. 9. Dynamic Soil-Structure Interaction of a Portal Frame Railway Bridge - Numerical Analysis on a Case Study Bridge

   University essay from KTH/Bro- och stålbyggnad

   Author : Rita Ikzer; [2018]
   Keywords : Dynamic Analysis; Soil-Structure Interaction; Damping; Railway Bridge; Portal Frame Bridge; Full FE-Modeling; Simplified Modeling; Dynamisk analys; Jord-struktur interaktion; Dämpning; Järnvägsbro; Plattrambro; Detaljerad FE-modellering; Förenklad modellering;

   Abstract : In the field of structural dynamics, a broader knowledge about relevant phenomena that affect the dynamic behavior of railway bridges is vital for structural engineers and design code administrators. The knowledge might benefit in an increased understanding of e.g. the resonance phenomena, and in improvements of the existing design codes. READ MORE

6. 10. Dynamic Soil-structure Interaction of Portal Frame Bridge Walls for High-speed Railways

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper
