  1. 1. Anchorage in Concrete Structures : Numerical and Experimental Evaluations of Load-Carrying Capacity of Cast-in-Place Headed Anchors and Post-Installed Adhesive Anchors

    Författare :Rasoul Nilforoush; Lennart Elfgren; Norbert Randl; Karin Lundgren; Manouchehr Hassanzadeh; Richard Malm; Lars-Erik Persson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Headed anchor; Anchor bolt; Adhesive anchor; Concrete cone breakout; Concrete splitting; Pullout loading; Size effect; Member thickness; Anchor head size; Orthogonal surface reinforcement; Concrete Strength; High-strength concrete; Cracked concrete; Steel fiber-reinforced concrete; Sustained loading; Creep behavior; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Various anchorage systems including both cast-in-place and post-installed anchors have been developed for fastening both non-structural and structural components to concrete structures. The need for increased flexibility in the design of new structures and strengthening of existing concrete structures has led to increased use of various metallic anchors in practice. LÄS MER

    Sammanfattning : The Swedish Transport Administration (STA) ambitiously strives to increase the level of productivity and innovation within its operations while meeting and surpassing national sustainability objectives. In this effort, the STA has concluded that climate gas emissions from construction, operation, and maintenance of the infrastructure must be reduced for Sweden to maintain its position as a pioneer and to reach both national and global climate goals.

  7. 5. 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
