  2. 16. Corrosion of steel bars in fibre reinforced concrete: corrosion mechanisms and structural performance

    Author : Carlos Gil Berrocal; 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; residual flexural capacity; chloride-induced corrosion; electrical resistivity; Fibre reinforced concrete; reinforcement bond; durability; cracking;

    Abstract : The viability of employing fibre reinforcement to improve the durability performance of RC structures by delaying and/or reducing rebar corrosion and by mitigating the structural impact of corrosion-induced damage have been investigated. Given the enhanced crack control of FRC, it could be advantageous to use fibres in civil engineering structures to decrease the ingress of corrosion-initiation substances. READ MORE

  4. 17. Assessment of fatigue resistance and strength in existing concrete structures

    Author : Håkan Thun; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : During the last few decades, it has become more and more important to assess, maintain and strengthen structures like bridges, dams and buildings. This is mainly due to the fact that: (a) many structures are getting old and many have started to deteriorate, (b) there is sometimes a need to increase the load carrying capacity of an existing structure due to e.

  5. 18. Control of Cracking due to Imposed Strains in Concrete Structures

    Author : Dan Pettersson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; Friction.; Restraint; Shrinkage; Imposed deformations; Minimum reinforcement; Crack widths; Reinforced concrete; Crack development; Crack control; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : This thesis is concerned with crack control due to imposed deformations in concrete structures. The objective of crack control may either be to prevent cracking or to limit the crack widths. The aim here is to increase the knowledge in both fields for some common structures. Five papers are included and the three last concern crack development. READ MORE

  6. 19. Fracture mechanics analysis of concrete structures

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

    Abstract : This thesis presents results from numerical and analytical analyses of concrete structures as well as results from laboratory tests. Numerical methods based on the finite element method and fracture mechanics are used. The thesis comprises five papers and a general introductory part. READ MORE

  7. 20. Usability of Textile Reinforced Concrete: Structural Performance, Durability and Sustainability

    Author : Natalie Williams Portal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainability; life cycle assessment; experimental methods; finite element analysis; durability; Textile reinforced concrete;

    Abstract : Textile reinforced concrete (TRC) is an innovative high performance composite material consisting of open multi-axial textiles embedded in a fine-grained concrete matrix. Despite the fact that TRC-based research has revealed many promising attributes, it has yet to reach its recognition due to a lack of available design tools, standards and long-term behaviour.
