  5. 34. Soil-Structure Interaction Analysis of Portal Frame Railway Bridges : Numerical Analysis of Two Case Study Bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Nils Sandqvist; Marko Milicevic; [2020]
    Keywords : Soil-structure Interaction; Portal Frame Bridge; Dynamic Analysis; Perfectly Matched Layer; Train Passage Analysis; Railway Bridge; High Speed Train v;

    Abstract : This thesis concerns dynamic Soil-Structure Interaction (SSI) analysis of portal framerailway bridges. Dynamic problems are common for bridges used for high speedrailway traffic. The passing trains induce harmonic loads on the bridges causingvibration amplitudes that may cause damage to the bridge structures and userdiscomfort. READ MORE
