  2. 1. 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

  4. 2. 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

  5. 3. Fibres in reinforced concrete structures - analysis, experiments and design

    Author : Anette M Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crack width; stress crack-width relationship; design methods; post cracking; analysis method; Fibre-reinforced concrete;

    Abstract : Potential benefits from fibres in concrete are improved crack control and the possibility of more slender structures. The extent of the crack control depends, among other factors, on the amount of fibres added, and plays a great role for durability. READ MORE

  6. 4. Reinforcement in Tailor-made Concrete Structures

    Author : David Fall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailor-made concrete structures; Steel fibre reinforcement; Automated production; Geometrically complex structures; Reinforcement alternatives;

    Abstract : In tailor-made concrete structures of complex geometries, the formability of concrete is an asset. To use this formability in load-bearing structures, the concrete needs to be reinforced. During the past century steel bars were used; however, in recent decades, alternative reinforcement methods have been introduced. READ MORE

  7. 5. Cracking in concrete : crack prevention with air-cooling and crack distribution with steel fibre reinforcement

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

    Abstract : This Licentiate Thesis consists of four parts. The first two parts, paper A and B, deal with air-cooling by means of embedded pipes in order to reduce thermal cracking in concrete structures. These two papers are submitted for publication to RILEM Journal; ‘Materials and Structures'. READ MORE
