    Författare :Hans Pétursson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Broar med integrerade landfästen har blivit allt populärare i bl.a. USA, Kanada och Storbritannien. Den främsta orsaken sägs vara de låga underhållskostnaderna. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
