  1. 21. Tensile behaviour of mineral-based composites

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

    Sammanfattning : Externally bonded fibre-reinforced polymer (FRP) systems have shown to be a robust and durable way to repair, or strengthen concrete structures. Epoxy, as the most common bonding agent, provides excellent force transfer, and bonds well to the base substrate to the as well as to the strengthening material. LÄS MER

  3. 22. Assessment of shear and energy‐absorption capacity of reinforced concrete elements under impulsive loads

    Författare :Viktor Peterson; Anders Ansell; Mikael Hallgren; Yanyan Sha; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Impulsive loads; impact; blast; shear reinforcement; shear failure; Betongbyggnad; Concrete Structures;

    Sammanfattning : Impulsive loads have been observed to cause brittle shear failure in reinforced concrete elements designed for ductile failure modes under static loads. Brittle failure modes exhibit poorer energy absorption capabilities compared to ductile flexural failure modes due to their limited deformation capacity, leading to premature failure. LÄS MER

  4. 23. Seismic high-frequency content loads on structures and components within nuclear facilities

    Författare :Cecilia Rydell; Anders Ansell; Mario Plos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear power plant; Earthquake; Seismic high frequencies; Fluid-structure interaction; Piping; Concrete; Pool;

    Sammanfattning : Sweden is generally considered to be a low seismicity area, but for structures within nuclear power facilities, the safety level demand with respect to seismic events are high and thus, these structures are required to be earthquake-resistant. The seismic hazard is here primarily considered to be associated with near-field earthquakes. LÄS MER

  5. 24. Data based configuration decisions in hospital construction projects

    Författare :Pia Schönbeck; Anders Ansell; Malin Löfsjögård; Carmel Lindkvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information management; Configuration management; Decision support; Hospital buildings; Concrete Structures; Betongbyggnad;

    Sammanfattning : The purpose of hospital buildings is to enable the diagnosis, treatment and caring of patients. Hospital configurations are therefore complex and deficient functionality at the final delivery of construction projects are a known issue. Configuration management is essential to ensure that all required functions are fulfilled. LÄS MER

  7. 25. Use of configuration information in construction projects to ensure high performance of healthcare facilities

    Författare :Pia Schönbeck; Anders Ansell; Malin Löfsjögård; Göran Lindahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; configuration management; information management; project management; product management; healthcare facilities; Byggvetenskap; Civil and Architectural Engineering; Concrete Structures; Betongbyggnad;

    Sammanfattning : The transfer of information between the different phases of construction projects is limited, which complicates the quality assurance of configurations. Functional requirements on the building configuration are often ambiguous and lack measurable acceptance criteria. LÄS MER
