    Author : Fredrik Gränne; KTH; []
    Keywords : Roofing; roof membrane; durability; waterproofing; leakage; wind-load; non-destructive testing; NDT; BSL4; BLS3; air leakage; building envelope;

    Abstract : The purpose of this work is to contribute to a process formaking buildings with good function and to avoid prematurefaults.The design, construction and installation of low-slopedroofs are important parts of creating a durable building. READ MORE

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

    Author : Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 18. Segmented HPGe detectors for post-irradiation examination of nuclear fuel : Design and demonstration in gamma emission tomography

    Author : Vikram Rathore; Peter Andersson; Erik Andersson Sundén; Ane Håkansson; Andrew Boston; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Segmented HPGe detector; Nuclear fuel; Post-irradiation examination; Nuclear fuel diagnostics; Gamma emission tomography; Gamma spectroscopy; Non-destructive fuel testing; Applied Nuclear Physics; Tillämpad kärnfysik;

    Abstract : Gamma emission tomography (GET) is a proven non-invasive technique for post-irradiation examination of nuclear fuel. In the past, collimated HPGe detectors were used for GET measurements due to their good energy resolution. READ MORE

  6. 19. Spherical Indentation Technique for Multiscale Characterisation of Asphalt Mixtures

    Author : Hassan Fadil; Denis Jelagin; Manfred Partl; Per-Lennart Larsson; Said Safwat; Eshan Dave; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building Materials; Byggnadsmaterial;

    Abstract : The viscoelastic properties of asphalt  mixtures  strongly  influence the  performance of flexible pavements  with respect to  their resistance to several common distress modes. Therefore, accurate measurement of these properties and their change during the service life is an important area of ongoing research. READ MORE

  7. 20. Application of Automated Non-contact Resonance Testing for Low Temperature Behavior of Asphalt Concrete

    Author : Abiy Bekele; Nils Ryden; Safwat Said; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resonance testing; stiffness modulus; asphalt concrete; Non-contact excitation; Resonance frequency; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Impact resonance testing is a well-documented non-destructive testing method and its applications on asphalt concrete have also been implemented successfully. The test is carried out manually by inducing an impact in order to excite the test specimen and taking measurements of the vibrational response. READ MORE
