  1. 1. Shear and Torsion in Concrete Structures Non-linear Finte Element Analysis in Design and Assessment

    Författare :Helén Broo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; torsion; box-girder bridge; hollow core unit; hollow core floor; non-linear finite element analysis.; shear; prestressed concrete; Reinforced concrete;

    Sammanfattning : For structural design and assessment of reinforced concrete members, non-linear finite element analysis has become an important tool. However, design and assessment of shear and torsion are still done with simplified analytical or empirical design methods. LÄS MER

  3. 2. Predicting shear type crack initiation and growth in concrete with non-linear finite element method

    Författare :Richard Malm; Håkan Sundquist; Anders Ansell; Kent Gylltoft; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear finte element analysis; concrete; crack width; crack propagation; shear; Building engineering; Byggnadsteknik;

    Sammanfattning :   In this thesis, the possibility to numerically describing the behaviour that signifies shear type cracking in concrete is studied. Different means for describing cracking are evaluated where both methods proposed in design codes based on experiments and advanced finite element analyses with a non-linear material description are evaluated.
