  2. 1. Plate buckling resistance : patch loading of longitudinally stiffened webs and local buckling

    Author : Mattias Clarin; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : Incremental launching of steel bridges is a demanding undertaking, on the erection site as well as on the designers desk. Not seldom, the structure itself is during the launching subjected to high concentrated forces on the lower flange when passing over the launching shoe or a intermediate support (e.g. column).

  4. 2. Stainless Steel Corrugated Web Girders for Composite Road Bridges: Concept Evaluation and Flange Buckling Resistance

    Author : Fatima Hlal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Investment cost; Genetic algorithm; Duplex stainless steel; LCC; Corrugated web; Flange buckling resistance; Optimization; Composite bridges; LCA; Road bridges;

    Abstract : Achieving a sustainable bridge design requires careful consideration of economic viability and environmental impact over the entire lifespan of the structure. While stainless steel is recognized for its excellent life cycle performance, its high cost prevents it from being used to a larger extent in bridges. READ MORE

  5. 3. Structural Design of Laser-Welded Sandwich Panels for Marine Applications

    Author : Hans Kolsters; KTH; []
    Keywords : Sandwich; Laser welding; Web; Core; Stiffness; Elastic Buckling; Ultimate strength; Finite element analysis; Mechanical testing; Optimisation.;

    Abstract : In shipbuilding the replacement of stiffened platestructures by laser-welded sandwich panels offers considerableadvantages for production as well as vessel operation. In viewof reduced weight and space requirements an area of particularinterest is the incorporation of an adhesively bonded core bywhich the stiffness and strength can be substantiallyincreased, and thermal-acoustic insulation can be integrated.

  6. 4. Column buckling with restraint from sandwich wall elements

    Author : Eva Hedman-Petursson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Sandwich wall elements are often used as cladding on industrial buildings together with a steel framing. This thesis deals with the restraining effect of a sandwich element wall on steel beam-columns. READ MORE

  7. 5. On some Fatigue Problems Related to Steel Bridges

    Author : Roberto Crocetti; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modular bridge expansion joints; full-scale testing; web breathing; postbuckling behaviour; fatigue; riveted connections;

    Abstract : This thesis concerns three specific fatigue topics related to steel members in bridges, namely: (1) Modular Bridge Expansion Joints (MBEJs). Several premature fatigue failures of MBEJs have occurred in Europe and USA during the past decades. READ MORE
