  1. 11. Reliable Assessments of Concrete Structures with Corroded Reinforcement: An Engineering Approach

    Författare :Mattias Blomfors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anchorage; safety formats.; reliability; reinforced concrete structures; bond; finite element modelling;

    Sammanfattning : When in service, concrete structures are inevitably exposed to detrimental processes which, over time, can affect the structures’ ability to fulfil their structural requirements. The most common cause of deterioration of concrete structures is corrosion of the reinforcement; a problem that is expected to become more severe in future, due to climate change. LÄS MER

  3. 12. Natural corrosion in reinforced concrete structures

    Författare :Samanta Robuschi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural corrosion; pitting corrosion; reinforced concrete structures; chloride-induced corrosion.; neutron imaging; anchorage; plain bars; X-rays CT;

    Sammanfattning : Among the threats to the durability of concrete structures, corrosion of the reinforcement bars is undoubtedly the most common one. Corrosion damages impair safety and durability of infrastructure, and assessment of the safety is challenging due to the complex nature of the corrosion process. LÄS MER

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

    Författare :Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 14. Mechanical anchorage of prestressed CFRP tendons : theory and tests

    Författare :Anders Bennitz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Fibre Reinforced Polymers (FRPs) are slowly becoming important materials to consider also for a structural engineer. They are light-weight, insensitive to corrosion and have highly modifiable mechanical properties. LÄS MER

  7. 15. Cell cycle control by components of cell anchorage

    Författare :Annica Gad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Extracellular factors, such as growth factors and cell anchorage to the extracellular matrix, control when and where cells may proliferate. This control is abolished when a normal cell transforms into a tumour cell. The control of cell proliferation by cell anchorage was elusive and less well studied than the control by growth factors.
