  1. 11. Shear walls for multi-storey timber buildings

    Författare :Johan Vessby; Hilmer Riberholt; Växjö universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-storey structures; timber engineering; wind stabilization; shear walls; cross-laminated timber wall panels; fasteners; connections; sheathing; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

    Sammanfattning : Wind loads acting on wooden building structures need to be dealt with adequately in order to ensure that neither the serviceability limit state nor the ultimate limit state is exceeded. For the structural designer of tall buildings, avoiding the possibly serious consequences of heavy wind loading while taking account at the same time of the effects of gravitation can be a real challenge.

  3. 12. Numerical modelling of fluid flow and particle transport in rough rock fracture during shear

    Författare :Tomofumi Koyama; Lahru Jing; Auli Niemi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; single rock fracture; coupled stress-flow test; shear displacement; fluid flow; particle; Geoengineering; Geoteknik;

    Sammanfattning : The effects of different shearing processes and sample sizes on the fluid flow anisotropy and its impact on particle transport process in rough rock fractures are significant factors that need to be considered in the performance and safety assessments of underground nuclear waste repositories. The subjects, however, have not been adequately investigated previously in either laboratory experiments or numerical modeling. LÄS MER

  5. 14. Nonlinear Numerical Simulations of Interactions Between Ice Rubble and Structure

    Författare :Aniket Patil; Andrzej Cwirzen; Björnar Sand; Lennart Fransson; Knut Vilhelm Høyland; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ice mechanics; ice rubble; sea ice ridges; punch through test; shear box test; friction coefficient; cohesive element method; smoothed particle hydrodynamics; continuous surface cap model; numerical modelling; Byggkonstruktion; Structural Engineering;

    Sammanfattning : This research is focused on three distinct but interconnecting topics:1) investigation of physical and mechanical properties of ice rubble, 2) material modelling of ice rubble, 3) numerical simulation of the interaction between ice rubble structure interaction. large scatter in the values of physical and mechanical properties of ice rubble can be seen in the literature due to non-standardised methods.

  7. 15. Shear walls with double plasterboards : evalutation of design models

    Författare :Tomas Filipsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : This thesis presents a part of the ECSC-project Development of dry composite construction systems based on steel in residential application that focus on design recommendations for stabilizing buildings by using shear resistance in the walls. The existing design method suggested and used by the Swedish plasterboard manufacturer Gyproc AB is considered as a bit conservative and it does not consider double plasterboards properly. LÄS MER
