  2. 16. Prestressed hybrids of AAC and HPC : The BCE (Block Composed Element) building system. A conceptual study

    Author : Hamid Bagheri; Bo Göran Hellers; Jonas Holmgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture and architectural conservation and restoration; Arkitektur och bebyggelsevård;

    Abstract : There is an important potential for a development of a building system, if the present AACblock plants are completed with high performance concrete and pre-stressing technique. This can be done as a continuation of a present AAC production or in a site factory. Hybrid cooperation between AAC and concrete is not a new technology. READ MORE

  4. 17. Assessment of prestressed concrete bridges loaded in combined shear, torsion and bending : uncertaintiers in deterministic and statistic methods

    Author : Arto Puurula; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The aim of the thesis is to investigate the load-carrying capacity of bridges according to different models for shear in combination with bending, torsion and prestressing. The following models are studied: Model with traditional summation of the contributions from concrete and steel accroding to the Swedish Code BBK 94 Strut model according to the European code EC2 Modified Compression Field Theory from Canada The models are applied to the Källösund Bridge on the road to the island Tjörn on the West coast of Sweden.

  5. 18. Mechanical anchorage of prestressed CFRP tendons : theory and tests

    Author : Anders Bennitz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Fibre Reinforced Polymers (FRPs) are slowly becoming important materials to consider also for a structural engineer. They are light-weight, insensitive to corrosion and have highly modifiable mechanical properties. READ MORE

  6. 19. Structural integrity of prestressed nuclear reactor containments

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

    Abstract : 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. READ MORE
