  1. 1. Flexible culverts in sloping terrain : Research advances and application

    Författare :Amer Wadi; Raid Karoumi; Lars Pettersson; Jan Vaslestad; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible culvert; Soil‒steel composite bridge; Sloping terrain; Swedish design method; Finite element model; Slope stability; Avalanche load; Snowshed; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Although the construction of flexible culverts involves simplicity in comparison to similar concrete structures, the complexity of the beneficial interaction between soil and steel materials requires good understanding for their composite action and performance. Current design methods have certain validity limitations with regard to applicable slopes above the structures. LÄS MER

  2. 2. Soil-Steel Composite Bridges : Research advances and application

    Författare :Amer Wadi; Raid Karoumi; Lars Pettersson; Ian D. Moore; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Flexible culvert; Soil‒steel composite bridge; Sloping terrain; Swedish design method; Finite element model; Ultimate capacity; Avalanche load; Failure load; Low soil cover; Failure mechanism; Long-span; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Soil-steel composite bridges are considered competitive structures being an economical alternative to similar span concrete bridges. This frequently stimulates practitioners to push their design limits and expand the different areas of application including their performance in sloping terrain. LÄS MER
