  1. 16. Dynamic fail-safe behaviour of steel structures

    Författare :Ulf Arne Girhammar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The fundamental behaviour and the capacity of steel structures subjected to loss of interior load-bearing elements are studied. The ultimate load-bearing and deformation capacity of certain beam-to-column connections and the dynamic fail-safe behaviour of some ordinary steel structures are investigated in detail. LÄS MER

  3. 17. Behaviour of Piles with Enlarged Tip in Non-Cohesive Soil. Model Tests and Numerical Simulations

    Författare :Torbjörn Edstam; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerical simulations; plasticity; model tests; enlarged tip; piles; large strains; sand;

    Sammanfattning : Slender piles reduce detrimental vibrations during installation. In order to preserve a high bearing capacity, the pile tip can be enlarged after installation. This study consists of model tests of conventional piles (unexpanded piles) and piles with enlarged tip (expanded piles). LÄS MER

  4. 18. STRUCTURAL RETROFITTING OF CONCRETE BEAMS USING FRP - Debonding Issues

    Författare :Yasmeen Obaidat; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A 3D nonlinear finite element analysis modelling framework was developed for simulating the behaviour of beams retrofitted with fibre reinforced polymer (FRP). The ABAQUS program was used for this purpose. Concrete was modelled using a plastic damage model. LÄS MER

  5. 19. Strengthening of concrete structures with CFRP : shear strengthening and full scale applications

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

    Sammanfattning : Structures can be in need of strengtheing due to many reasons, which are presented in this thesis. A literature review gives the existing methods for enhancing a structures load bearing capacity. In this thesis focus will be set at external bonding with carbon fibre reinforced polymers. LÄS MER

  7. 20. Composite Columns of Hollow Steel Sections Filled with High Strength Concrete

    Författare :Marianne Grauers; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the design of buildings today, great effort is made to increase the structural flexibility. This has resulted in a demand for columns with reduced cross sections. To achieve a high load bearing capacity with a small cross sectional area, it is worthwhile to study the possibility of utilizing high strength concrete and composite effects. LÄS MER
