  1. 6. 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

  3. 7. Concrete flat slabs and footings : Design method for punching and detailing for ductility

    Författare :Carl Erik Broms; Håkan Sundquist; Mikael Hallgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; bent-down bars; building codes; cyclic loading; deflection; ductility; earthquake; Byggnadsteknik; Building engineering; Byggnadsteknik;

    Sammanfattning : Simple but still realistic physical models suitable for structural design of flat concrete plates and column footings with respect to punching are presented. Punching of a flat plate is assumed to occur when the concrete compression strain at the column edge due to the bending moment in the slab reaches a critical value that is considerably lower than the generally accepted ultimate compression strain 0.

  4. 8. Numerical experiments - a research method in fire science

    Författare :Nils Johansson; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental uncertainty; accuracy; fire dynamics; compartment fires; models; experiments; Numerical experiments;

    Sammanfattning : Fires are complex and it is hard to derive relationships from theory in fire science. Full-scale and small-scale experiments have been used with great success in order to increase the understanding of fire chemistry and fire dynamics. But, there are shortcomings and difficulties with conducting these traditional fire experiments. LÄS MER
