  2. 1. Shear in Concrete Structural Elements Subjected to Dynamic Loads

    Author : Johan Magnusson; Anders Ansell; Mikael Hallgren; Richard Malm; Jaap Weerheijm; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic load; initial response; shear failure; shear capacity; numerical simulations; bond; shear span; support reactions; Dynamisk last; initial respons; skjuvbrott; skjuvkapacitet; numeriska simuleringar; förankring; skjuvspännvidd; upplagsreaktioner; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Concrete structural elements subjected to severe dynamic loads such as explosions at close range may cause shear failures. In the Oklahoma City bombing in 1995 two concrete columns on the ground level were reported to have failed in shear. READ MORE

  4. 2. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system

    Author : Anders Kullingsjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIT-S1; Sheet pile wall; Soil-structure interaction; Strain; Stress; Ground surface settlement; Finite element method; Case history; Shear test; Shear strength; Pore pressure; Analysis; Constitutive models; Plane strain; Elastoplasticity; Laboratory tests; Factor of safety; Stiffness; e-ADP; Earth pressure; Anisotropy; Soft Clay; Deep excavation; Retaining wall; Shear stress; Deformation;

    Abstract : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. READ MORE

  6. 4. Mechanical Behavior of Tailings : Laboratory Tests from a Swedish Tailings Dam

    Author : Riaz Bhanbhro; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailings dams; Tailings; Mechanical Behavior; Oedometer; Direct Shear; Triaxial; Shear strength; Soil Mechanics; Geoteknik;

    Abstract : Tailings is leftover material from mining industry and is produced in huge quantities approximately 70-99% of the ore production.  Tailings material is stored as impoundments by constructing tailings dams which are often constructed with tailings material itself. READ MORE

  7. 5. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge

    Author : Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anchorage; carbon fibre reinforced polymers; concrete; existing bridges; finite element analysis; flexure; full-scale test; load-carrying capacity; residual prestress force; punching; safety verification; shear; structural assessment; structural behaviour; Structural Engineering; Konstruktionsteknik;

    Abstract : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. READ MORE
