1. 1. 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

3. 2. 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.

4. 3. 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

5. 4. Dynamic Soil-structure Interaction of Portal Frame Bridge Walls for High-speed Railways

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

   Author : Henrik Malm; [2016]
   Keywords : SSI; Soil-structure interaction; Structural dynamics; High-speed railway bridges; Impedance; Receptance; Finite element method; Portal frame bridge; Technology and Engineering;

   Abstract : In Sweden, high-speed railways is a subject for public debate. The first stage of a high-speed train network, Ostlänken between Stockholm and Linköping, is under investigation, and is planned to be trafficked in 2028. The high-speed railway is intended to hold traffic with speeds up to 320 km/h. READ MORE

6. 5. Soil-structure interaction of end-frames for high-speed railway bridges

   University essay from KTH/Bro- och stålbyggnad

   Author : Johan Östlund; [2016]
   Keywords : Dynamics; SSI; Soil-structure interaction; Soil-bridge interaction; HSR; High-speed railway; Impedance; Receptance; End-frame bridge; Dynamik; SSI; Jord-struktur interaktion; Jord-bro interaktion; HSR; Höghastighetsbana; Höghastighetståg; Impedans; Receptans; Ändskärmsbro;

   Abstract : In this thesis, the influence of soil-structure interaction (SSI) of end-frame bridges for high-speed railways was studied. Impedance functions, representing the SSI, was calculated and analyzed. The impedance functions were applied to end-frame bridge models which were analyzed for use in HSR. READ MORE
