  2. 11. Design of steel piles for integral abutment bridges

    Author : Hans Petursson; Ian May; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integral abutment bridges; steel piles; jointless bridges; Steel Structures; Stålbyggnad;

    Abstract : In 1999 research was started at Luleå University of Technology with the purpose to collect experiences from USA and UK on bridges with integral abutments and transfer the experience to Swedish conditions. Since then at least 20 integral bridges with one row of piles under each abutment have been built in Sweden and the European research project INTAB has been completed. READ MORE

  4. 12. On failure of high strength steel bridge roller bearings

    Author : Pourya Noury; Ove Lagerqvist; Kjell Eriksson; John Yates; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Abstract : This thesis is concerned with failure analysis of high strength steel bridge roller bearings.Paper Adescribes how the commonly used Hertz formulas for contact stresses underestimate the actual stresses in practice due to temperature differences, misalignments and other construction-related conditions.

  5. 13. Thin-walled steel studs in fire : analysis and design recommendations

    Author : Peter Karlström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : Development of steel frame modular buildings is gaining increased popularity and support throughout Europe. Due to flexibility in construction and good long-term performance, lightweight steel frame structures are often preferred solutions, for instance in partitions and suspended ceilings as well as for load-bearing elements.

  6. 14. Patch loading of stainless steel girders : experiments and finite element analyses

    Author : Emma Unosson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : This thesis deals with the behaviour of stainless steel girders subjected to patch loading. The current loading situation arises for example at beam- column connections or at crane girders where the load is travelling along a girder. At bridge launching it is also important to consider patch loading. READ MORE

  7. 15. Plastic design of steel bridge girders

    Author : Frank Axhag; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : This thesis assesses the feasibility of a modified plastic design method for continuous steel or composite bridges with slender I-girders. The feasibility evaluation of the design method is closely connected to the moment-rotation relationship of the I-girders at internal supports. READ MORE
