  2. 16. On inelastic local flange buckling

    Author : Mikael Möller; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik; Steel Structures; Stålbyggnad;

    Abstract : This thesis deals with inelastic local buckling of I-beam flanges made of steel. The main focus is on the theoretical description of the buckling process, and the influence of various parameters, e.g. the plastic modulus, yield plateau, yield stress etc. READ MORE

  4. 17. Using Trees to Capture Reticulate Evolution : Lateral Gene Transfers and Cancer Progression

    Author : Ali Tofigh; Jens Lagergren; Mike Steel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lateral Gene Tranfer; Horizontal Gene Transfer; Cancer Progression; Bioinformatics; Bioinformatik; Computer science; Datalogi;

    Abstract : The historic relationship of species and genes are traditionally depicted using trees. However, not all evolutionary histories are adequately captured by bifurcating processes and an increasing amount of research is devoted towards using networks or network-like structures to capture evolutionary history.

  5. 18. Flexural Buckling of High-Strength Steel Columns

    Author : Gabriel Sabau; Ove Lagerqvist; Torsten Höglund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Abstract : The European standards dealing with design rules and recommendations for steel structures have been under revision in the past years due to the increased use of high-strength steels. High-strength steels popularity increased at a steady pace in the last decades since they allow for more light-weighted solutions than conventional steels. READ MORE

  6. 19. Steel Fibres in Reinforced Concrete Structures of Complex Shapes: Structural Behaviour and Design Perspectives

    Author : David Fall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometrically complex structures; Steel fibre reinforcement; Concrete structures; Reinforcement alternatives; Rational design;

    Abstract : In concrete structures of complex geometries, the formability of concrete is an asset.However, complex geometries introduce time-demanding form and reinforcement works. READ MORE

  7. 20. Patch loading : resistance of longitudinally stiffened steel girder webs

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

    Abstract : In most cases, longitudinal stiffeners increase the resistance of steel girder webs subjected to concentrated forces, commonly referred to as patch loading. During the last three decades, a number of experimental investigations have been undertaken in all over the world in this regard. READ MORE
