  2. 2. Static analysis of soil-steel composite bridges in sloping terrain

    Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Författare :Karina Skrobic; Josefine Bergström; [2014]
    Nyckelord :Flexible bridge; Culvert; Soil-steel; Sliding surfaces; Sloping terrain; PLAXIS; Interface; Pettersson-Sundquist design method; Flexibel bro; Kulvert; Jord-stål; Glidytor; Lutande terräng; PLAXIS; Gränsskikt; Pettersson- Sundquist dimensioneringsmetod;

    Sammanfattning : Soil-steel composite bridges are for many reasons very favorable bridges to build. Up to a certain span length they are economical, practical to transport and simple and quick to build. Especially in remote places, with unfavorable sloping terrain, this can be of great interest when the transport of material can be difficult and costly. LÄS MER

  3. 3. Soil Steel Composite Bridges for High-Speed Railways : 2D FEM analysis of the Björnbo Bridge

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Joakim Woll; [2014]

    Sammanfattning : This research aims to analyse the dynamic behaviour of Soil-Steel Composite Bridges when subjected by high-speed trains. the analyses of the dynamic response for these structures are needed since there is little research performed in the present field of knowledge. LÄS MER

  4. 4. Dynamic analysis of soil-steel composite railway bridges : FE-modeling in Plaxis

    Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Författare :Orod Aagah; Siavash Aryannejad; [2014]
    Nyckelord :Soil-steel composite bridge; Corrugated steel culvert; High-speed railways; FEM; Plaxis; Field measurements;

    Sammanfattning : A soil-steel composite bridge is a structure comprised of corrugated steel plates, which are joined with bolted connections, enclosed in friction soil material on both sides and on the top. The surrounding friction soil material, or backfill, is applied in sequential steps, each step involving compaction of the soil, which is a necessity for the construction to accumulate the required bearing capacity.
