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

    Abstract : This thesis is concerned with several aspects of fracture of both brackish (low salinity) sea ice and freshwater ice. The tests and analyses are confined to tensile, or in fracture mechanics language, Mode I, fracture. READ MORE

  3. 3. Institutional complexity in Swedish built environment regulation : exploring the interface with industrialized house-building

    Author : Viking Anders; Lars Stehn; Paul Chan; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : The industrialized house-building movement has emerged as aresponse to recurring criticism of the construction sector. It seeks toemulate management practices prevalent in manufacturing industries,including the use of standardized work processes and building systems. READ MORE

  4. 4. Energy efficiency strategies for residential buildings in a subarctic climate- impact on building energy use and indoor thermal climate

    Author : Shimantika Bhattacharjee; Lars Stehn; Sofia Lidelöw; Thomas Olofsson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggproduktion och teknik; Construction Management and Building Technology;

    Abstract : A large share of the building stock in Europe is old and its poor energy performance contributes to substantial energy use and greenhouse gas emissions. The old building stock is in need of renovation that can not only improve the building energy performance but can also improve the indoor thermal climate. READ MORE

  5. 5. Modal Analysis, Dynamic Properties and Horizontal Stabilisation of Timber Buildings

    Author : Ida Edskär; Helena Lidelöw; Lars Stehn; Thomas Nord; Thomas Reynolds; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : Engineers face new challenges as taller timber buildings are constructed. According to Eurocode 1-4, both horizontal deformations from static wind and acceleration levels shall be limited. Due to the low self-weight of wood, dynamic vibrations and acceleration levels cancause problems. READ MORE
