  2. 1. Fibre reinforced concrete : fracture mechanics methods applied on self-compacting concrete and energetically modified binders

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

    Abstract : Fibre reinforced concrete (FRC) is a type of building material that is increasing in use. As new types on concrete develops the need to update the knowledge on the use of fibre reinforcement increases. This thesis covers test methods for FRC that ranges from standard beam tests to sophisticated uniaxial tension tests. READ MORE

  4. 2. Concrete Structures Subjected to Blast and Fragment Impacts - Numerical Simulations of Reinforced and Fibre-reinforced Concrete

    Author : Ulrika Nyström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SDOF; Concrete; fragment impact; weapon effects; fibre-reinforced concrete; blast wave; numerical simulations; reinforced concrete;

    Abstract : Concrete is widely used in design of protective structures due to its good energy-absorbing characteristics under high pressures and, when properly reinforced, ductile behaviour. Nevertheless, the response of concrete structures subjected to severe dynamic loading differs from their static behaviour, on a structural level but also on a material level. READ MORE

  5. 3. Chloride Induced Corrosion of Steel Bars in Fibre Reinforced Concrete

    Author : Carlos Gil Berrocal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrical resistivity; chloride ingress; fibre reinforced concrete; crack width; reinforced concrete durability; chloride-induced corrosion;

    Abstract : Chloride-induced corrosion of reinforcement is the most widespread degradation mechanism affecting the durability of reinforced concrete structures. Macro-cracks provide a preferential path for moisture, oxygen and Cl ions to reach the embedded reinforcement, playing a major role in their total transport. READ MORE

  6. 4. Fibre-reinforced Concrete for Industrial Construction - a fracture mechanics approach to material testing and structural analysis

    Author : Ingemar Lövgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-situ cast; non-linear; self-compacting; fibre-reinforced; concrete;

    Abstract : ABSTRACTMore efficient and industrialised construction methods are both necessary for thecompetitiveness of in-situ concrete and essential if the construction industry is to moveforward. At present, the expenditure on labour (preparation and dismantling offormwork, reinforcing, and casting and finishing of concrete) almost equals the cost ofmaterial. READ MORE

  7. 5. FRP shear strengthening of reinforced concrete beams

    Author : Gabriel Sas; Giorgio Monti; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber reinforced polymers; shear; reinforced concrete; strengthening; model; comparison; literature review; Structural Engineering; Konstruktionsteknik;

    Abstract : The shear failure mechanisms of flexural reinforced concrete (RC) members is highly complex; its precise details cannot be explained with simple analytical relationships, and are the topic of considerable scientific debate. The studies described and examined the three most used shear theories in the world – the fixed angle truss model (45°TM), the variable angle truss model (VAT), and modified compression field theory (MCFT).
