  1. 1. Patch loading resistance of plated girders : ultimate and serviceability limit state

    Författare :Jonas Gozzi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : Patch loading or partial edge loading of steel girder webs is a load case where a concentrated force is introduced perpendicular to the flange of a girder. This usually induces a local failure of the girder web in the vicinity of the loaded flange. LÄS MER

  3. 2. Serviceability Limit State for Steel Girders during Bridge Launching - A Patch Loading Problem

    Författare :Per Granath; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel; patch loading; plate girders; bridge launching; post-buckling; behaviour; finite element analysis; serviceability limit state;

    Sammanfattning : Incremental launching is a construction method in which bridge girders are first assembled in the vicinity of the future permanent position of the bridge. When the elements have been welded together the girders are launched to their permanent position. LÄS MER

  4. 3. Investigations on the Serviceability Limit State of Dowel-Type Timber Connections

    Författare :Michael Dorn; de Borst Karin; Vienna University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timber engineering; dowel-type connection; experiments; simualations; Servieability Limit State; contact behavior; Byggteknik; Civil engineering;

    Sammanfattning : Dowel-type steel-to-timber connections are commonly used to transfer a large range of loads. Although they are simple to produce and assemble, the load-carrying behavior and the local stress and strain distribution within the connection area are highly complex. LÄS MER

  5. 4. Aspects of probabalistic serviceability limit state design of dry deep mixing

    Författare :Niclas Bergman; Stefan Larsson; Tim Länsivaara; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : An expanding population and increased need for infrastructure increasingly necessitate construction on surfaces with poor soil conditions. To facilitate the construction of buildings, roads and railroads in areas with poor soil conditions, these areas are often improved by means of foundation engineering. LÄS MER

  7. 5. On Probability in Geotechnics. Random Calculation Models Exemplified on Slope Stability Analysis and Ground-Superstructure Interaction

    Författare :Claes Alén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; random; creep; slope stability; calculation; interaction; design; limit state; probability; statistics; geotechnics;

    Sammanfattning : The thesis deals with uncertainty in calculation modelling. Emphasis is put on the design state. Design is a chain of decisions under uncertainty. A probabilistic approach is used to describe the uncertainty and calculations as a way to reveal the uncertainty. LÄS MER
