  2. 2. Dynamic soil-structure interaction of simply supported high-speed railway bridges

    Författare :Johan Lind Östlund; Jean-Marc Battini; Andreas Andersson; Mahir Ülker-Kaustell; Rui Calçada; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic soil-structure interaction; Railway bridge; Impedance function; Soil dynamics; High-speed train; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : Research performed on the subject of dynamic soil-structure interaction (SS) concerning railway bridges is presented in this thesis with the focus on simply supported railway bridges supported by shallow foundations in soil strata on bedrock. The research aims to obtain insight into the SSI of high-speed railway bridges and to provide recommendations on how to model the soil-bridge system from a design perspective. LÄS MER

    Sammanfattning : The work reported in this thesis presents a general overview of the dynamic response of short-span railway bridges considering soil-structure interaction. The study aims to identify the effect of the surrounding and underlying soil on the global stiffness and damping of the structural system. LÄS MER

  4. 4. Numerical modelling of geomaterials at failure

    Författare :Alex Spetz; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil-structure interaction; soil plasticity; phase-field fracture model; compression driven fractures; artificial rock; porous rock; finite element analysis; isogeometric analysis; NURBS; numerical methods;

    Sammanfattning : Geotechnical engineering is the science dealing with mechanics of soils and rocks and its engineering applications. Geotechnical engineering projects vary in a wide range, from evaluation of the stability of natural slopes and man-made soil deposits, to the design of earthworks and foundations. LÄS MER

  5. 5. Geotechnical Aspects of Buildings on Expansive Soils in Kibaha, Tanzania : Preliminary Study

    Författare :Charles Lucian; Staffan Hintze; Bo Berggren; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; expansive soils; soil properties; potential swell; Soil-Structure Interaction SSI ; and superstructure and substructure.; Building engineering; Byggnadsteknik;

    Sammanfattning : The focus of this study is on potential problems resulting from construction on expansive soils in Kibaha region, Tanzania. For the fact that most of the affected structures are founded on expansive soils, a clear understanding of the soil behaviour and their interaction with structures, specifically as they relate to shallow foundations, has been of more interest to the study in order to evaluate properly the source of the problem.
