  1. 1. Dynamic fail-safe behaviour of steel structures

    Author : Ulf Arne Girhammar; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : The fundamental behaviour and the capacity of steel structures subjected to loss of interior load-bearing elements are studied. The ultimate load-bearing and deformation capacity of certain beam-to-column connections and the dynamic fail-safe behaviour of some ordinary steel structures are investigated in detail. READ MORE

  2. 2. Modelling Alternative Load Paths in Platform-Framed CLT Buildings : A Finite Element Approach

    Author : Johannes Albert Josef Huber; Mats Ekevad; Ulf Arne Girhammar; Sven Berg; Sigurdur Ormarsson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; timber; robustness; finite element method; alternative load paths; disproportionate collapse; Träteknik; Wood Science and Engineering;

    Abstract : Timber has become more popular as a construction material during recent years. Engineered wood products, such as glued laminated timber and cross-laminated timber, have enabled the construction of multi-storey buildings. Tall buildings with many occupants need to resist a disproportional collapse in case of unexpected exposures, e.g. READ MORE

  3. 3. Numerical Modelling of Timber Building Components to Prevent Disproportionate Collapse

    Author : Johannes A. J. Huber; Sven Berg; Dick Sandberg; Mats Ekevad; Ulf Arne Girhammar; Jan-Willem G. van de Kuilen; Luleå tekniska universitet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; finite element modelling; alternative load paths; cross laminated timber; progressive collapse; CT scanning; fibre reconstruction; image analysis; Träteknik; Wood Science and Engineering;

    Abstract : An increasing number of multi-storey buildings are being constructed with engineered wood products, such as glulam or cross-laminated timber (CLT). Multi-storey timber buildings can be safely designed for foreseeable loads, but knowledge is limited concerning their ability to survive unforeseeable events, e.g. READ MORE

  4. 4. Analysis of shear wallsfor multi-storey timber buildings

    Author : Johan Vessby; Bo Källsner; Anders Olsson; Ulf Arne Girhammar; Roberto Crocetti; Linnéuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-storey structures; timber engineering; wind stabilization; shear walls; cross-laminated timber wall panels; fasteners; sheathing-to-framing connections; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

    Abstract : This doctoral thesis addresses questions of how wind loads acting on multistoreytimber buildings can be dealt with by structural design of such buildings.The conventional use of sheathing either nailed or screwed to a timberframework is considered, together with other stabilizing structures such ascross-laminated timber panels.

  5. 5. Architecturally Innovative Multi-Storey Timber Buildings : Methodology and Design

    Author : Axel Kaiser; London 8 Andrews Road Regent Studios Unit 3A/4A Ordinary Ltd; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : This investigation applies architectural ideas of mass-customised difference and repetition, and tests them within the engineering paradigm of very tall timber buildings – taller than have ever been erected in the history of architecture. According to Edward Glaeser’s book, Triumph of the City, the cheapest way to deliver new housing (at least in the USA) is in theform of mass-produced two-storey homes, which typically cost only about $84 per square foot to erect.
