  1. 11. Från grav till gård : romersk järnålder på Gotland

    Författare :Kerstin Cassel; Bjørn Olsen; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; North European; Arkeologi; nordeuropeisk; arkeologi; Archaeology;

    Sammanfattning : Houses with a stone foundation represent a new type of building on Gotland in the middle of the Roman Iron Age. At the same time there are other changes, for instance the number of visible graves decreases, and the farm and its land are emphasized by the stone enclosures that meander in the landscape. LÄS MER

  2. 12. Om att förstå ett hus : den dynamiska modellen : dokumentationsmetoder, vårdplan och restaureringsideologi

    Författare :Ebbe Hædersdal; Bebyggelsevård; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heritage values; restoration ideology; restoration; presentation; interpretation; fusion of horizons; hermeneutics; personal and tacit knowledge; buildings archaeology; buildings history; colour investigation; surveying; documentation methodlogy; Architectural heritage; documentation of historic buildings; digital maintenance plans.; Building construction; Byggnadsteknik; Architecture; interior design; Arkitektur; inredningsarkitektur; Archaeology; Arkeologi;

    Sammanfattning : The principal aim of the thesis is to evaluate the significance of the documentation of a building’s history for the work of restoring it and caring for it. Thus it may be said to address restoration as a hermeneutical problem, besides considering the relationships between the work of documentation; analyses of the resulting data; and the creative process in which the ideology of restoration is important.

  3. 13. 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
