  2. 1. Analytical and numerical approaches to estimate peak shear strength of rock joints

    Author : Francisco Ríos Bayona; Stefan Larsson; Fredrik Johansson; Diego Mas Ivars; José Muralha; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock joint; Shear strength; Failure criterion; Numerical shear tests; Bergsprickor; Skjuvhållfasthet; Brottkriterium; Numeriska skjuvförsök; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : In Sweden, there exists a large number of dams. Many of them are founded on rock masses normally affected by the presence of sub-horizontal rock fractures, which makes sliding along rock joints under the dam foundation one of the most critical failure mechanism. READ MORE

  4. 2. Development of prefabricated timber-concrete composite floors

    Author : Elzbieta Lukaszewska; Hans-Joachim Blass; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : Timber-concrete composite structures were originally developed for bridges and upgrading of existing timber floors, but finds today new applications in multi-storey buildings. Most of the research performed to date has been focused on systems where "wet" concrete is cast on top of timber beams with mounted connectors. READ MORE

  5. 3. Peak Shear Strength of Rock Joints – Towards a Methodology for Prediction Based on Field Data

    Author : Francisco Ríos Bayona; Fredrik Johansson; Diego Mas Ivars; Stefan Larsson; José Muralha; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock joints; peak shear strength; DEM; matedness; aperture; Bergssprickor; skjuvhållfasthet; DEM; sprickans passning; sprickvidd; Jord- och bergmekanik; Soil and Rock Mechanics;

    Abstract : The rock joint shear strength at field scale is an important design parameter and remains a challenge for rock mechanics engineers. In Sweden, there exist a large number of concrete dams that are founded on rock masses which in many cases contain sub-horizontal rock joints. READ MORE
