1. 1. Train Induced Vibration Analysis of an End-frame Bridge : Numerical Analysis on Sidensjövägen

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :Niklas Wiberg; Jasmin Halilovic; [2018]
   Nyckelord :Accelerations; Dynamics; End-frame bridge; FE-modeling; Frequency response function; High-speed railway; Soil structure interaction; Train induced vibrations; 2D 3D;

   Sammanfattning : 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.

   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
