  1. 1. Anchorage in Concrete Structures : Numerical and Experimental Evaluations of Load-Carrying Capacity of Cast-in-Place Headed Anchors and Post-Installed Adhesive Anchors

    Author : Rasoul Nilforoush; Lennart Elfgren; Norbert Randl; Karin Lundgren; Manouchehr Hassanzadeh; Richard Malm; Lars-Erik Persson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Headed anchor; Anchor bolt; Adhesive anchor; Concrete cone breakout; Concrete splitting; Pullout loading; Size effect; Member thickness; Anchor head size; Orthogonal surface reinforcement; Concrete Strength; High-strength concrete; Cracked concrete; Steel fiber-reinforced concrete; Sustained loading; Creep behavior; Structural Engineering; Konstruktionsteknik;

    Abstract : Various anchorage systems including both cast-in-place and post-installed anchors have been developed for fastening both non-structural and structural components to concrete structures. The need for increased flexibility in the design of new structures and strengthening of existing concrete structures has led to increased use of various metallic anchors in practice. READ MORE

  2. 2. Assessment of Concrete Structures Including Corrosion and Cracks

    Author : Mattias Blomfors; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; reinforcement bond; corrosion; reinforced concrete; nonlinear FE analysis; cracks;

    Abstract : Reinforced concrete (RC) structures constitute a major proportion of the built environment and society relies continuously on their service. Many of these structures were built in the era following the Second World War and are thus approaching the end of their intended service life. READ MORE

  3. 3. Steel fibre corrosion in cracks : durability of sprayed concrete

    Author : Erik Nordström; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Steel fibre reinforced sprayed concrete is common practice for permanent linings in underground construction. Today there is a demand on "expected technical service life" of 120 years. Thin steel fibres could be expected to discontinue carrying load fast with a decrease of fibre diameter caused by corrosion, especially in cracks. READ MORE

  4. 4. Durability of sprayed concrete : steel fibre corrosion in cracks

    Author : Erik Nordström; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : A combination of sprayed concrete technique and steel fibre technology gives obvious advantages when saving the work needed to place conventional reinforcement. In rock strengthening applications this is most accentuated. Sprayed concrete in general, made by skilled workmen, will generally be of high quality and good durability. READ MORE

  5. 5. Self-compacting concrete : properties of fresh and hardening concrete for civil engineering applications

    Author : Sofia Utsi; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This licentiate thesis consists of three papers, A-C. In Paper A the consequence of using self-compacting concrete for civil engineering applications regarding the fresh and young stage and possible consequences on production techniques are studied. READ MORE
