  1. 1. Structural integrity of prestressed nuclear reactor containments

    Författare :Patrick Anderson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel liner; reliability; relaxation; shrinkage; creep; loss of prestress; tendon; Nuclear; containment; design pressure; Construction technology; Anläggningsteknik;

    Sammanfattning : A nuclear power plant is provided with an extensive defense intended to prevent radioactive discharge in case of a reactor accident. This defense is built up of several independent safety barriers, where the reactor containment constitutes the last barrier to the environment. LÄS MER

  3. 2. Hydro-mechanical properties of a water unsaturated sodium bentonite. Laboratory study and theoretical interpretation

    Författare :Ann Dueck; Institutioner vid LTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Anläggningsteknik; Material technology; Construction technology; materialteknik;

    Sammanfattning : Highly compacted bentonite has been proposed as the buffer material in the Swedish concept for the disposal of nuclear waste. To increase the knowledge of the hydro-mechanical behaviour of unsaturated swelling bentonite a series of laboratory experiments was carried out. LÄS MER

  4. 3. Property-Oriented Information Systems for Design Prototypes for the BAS•CAAD system

    Författare :Sverker Fridqvist; Byggproduktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anläggningsteknik; Construction technology; product modelling; construction; information technology; design; Data- och systemvetenskap; computer technology; Systems engineering;

    Sammanfattning : Property-oriented systems are a new kind of information systems that are based on concepts of properties instead of concepts of things or classes of things. By focusing on properties, the property-oriented systems become more flexible and more suited to the dynamic early stages of design than the traditional class-oriented systems can be. LÄS MER

  5. 4. Probabilistic System Effects in Timber Structures

    Författare :Martin Hansson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Anläggningsteknik; Construction technology; first order reliability method; Monte Carlo simulation; system effect; sheathed parallel member system; structural timber; roof truss;

    Sammanfattning : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. LÄS MER

  7. 5. Seaside, Celebration och Windsor: Studier av urbana estetiska regler

    Författare :Mats Hultman; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :HUMANIORA; HUMANITIES; Arkitektur; interior design; Architecture; Anläggningsteknik; Construction technology; Windsor; Celebration; Seaside; New Urbanism; design codes; aesthetic rules; urban; aesthetics; quality; inredningsarkitektur;

    Sammanfattning : This dissertation deals with aesthetic rules in an urban context. The dissertation develops a theoretical framework for understanding the role of aesthetic rules, especially urban design codes, in the process of improving the architectural quality of the built environment.
