  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. Composite Bridges : Innovative ways of achieving composite action

    Författare :Robert Hällmark; Peter Collin; Ian May; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite action; bridges; steel; concrete; shear connectors; prefabrication; coiled spring pins; shear studs; post-installation; design guidance; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The topic of this thesis is steel-concrete composite bridges and innovative ways of achieving composite action. The typical superstructure consists of three main components: the steel girders, the concrete deck slab and the shear connectors. LÄS MER

  5. 4. Stress-laminated-timber bridge decks subjected to ultimate loads

    Författare :Kristoffer K J Ekholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultimate-load tests; Stress-laminated timber; Timber bridges;

    Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from several deck laminations positioned side by side. LÄS MER

  7. 5. 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
