  1. 11. Structural Control and Identification of Civil Engineering Structures

    Författare :Tarek Edrees; Francesc Pozo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : In general, the main purpose of a structural control system is to apply powerful control techniques that improve the behaviour of civil structures under various kinds of dynamic loading. The first part of this thesis presents novel applications of posicast and input shaping control schemes that have never previously been applied in the field of structural control. LÄS MER

  3. 12. Vibrations in lightweight structures - Efficiency and reduction of numerical models

    Författare :Ola Flodén; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Multi-storey wood buildings have been increasing in popularity since a century-old ban on the construction of such buildings was lifted in 1994. Compared to conventional concrete structures, it is more difficult to build lightweight structures in such a way that noise and disturbing vibrations is avoided. LÄS MER

  4. 13. Timber volume element prefabrication : production and market aspects

    Författare :Matilda Höök; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : Problems discussed within the Swedish housing industry are lack of competition, quality and increased costs. Improvements to cope with these problems have shown to be low compared to manufacturing and other industries. LÄS MER

  5. 14. Analysis of Catenary Effect in Steel Beams and Trusses Exposed to Fire

    Författare :Naveed Iqbal; Paulo Vila Real; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : The goals of structural design are fundamentally different when designing structures at normal temperature or when designing them in a fire situation. While structures are primarily designed for normal temperature situations considering the different design limit states, in the fire design situation, however, the already designed structure is assessed for its resistance in the fire design limit state.

  7. 15. Development of prefabricated timber-concrete composite floors

    Författare :Elzbieta Lukaszewska; Hans-Joachim Blass; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : Timber-concrete composite structures were originally developed for bridges and upgrading of existing timber floors, but finds today new applications in multi-storey buildings. Most of the research performed to date has been focused on systems where "wet" concrete is cast on top of timber beams with mounted connectors. LÄS MER
