  2. 21. STRUCTURAL RETROFITTING OF CONCRETE BEAMS USING FRP - Debonding Issues

    Author : Yasmeen Obaidat; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : A 3D nonlinear finite element analysis modelling framework was developed for simulating the behaviour of beams retrofitted with fibre reinforced polymer (FRP). The ABAQUS program was used for this purpose. Concrete was modelled using a plastic damage model. READ MORE

  4. 22. CFRP strengthening of concrete slabs, with and without openings : experiment, analysis, design and field application

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

    Abstract : Rehabilitation and strengthening of concrete structures with externally bonded FRP (Fibre Reinforced Polymers) has been a viable technique for at least a decade. The most common way to strengthen a structure is in flexure where thedesign normally follows traditional concrete design, with exceptions for control of bond and anchorage related to the FRP.

  5. 23. Numerical analysis of concrete elements strengthened with carbon fiber reinforced polymers

    Author : Joakim Lundqvist; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Due to the growing number of ageing reinforced concrete structures such as buildings and bridges, there is an increasing interest in condition assessment and strengthening methods. Deterioration processes and demands for higher loads contribute to this interest. READ MORE

  6. 24. Shrinkage cracking of steel fibre reinforced self compacting concrete overlays: test methods and theoretical modelling : test methods and theoretical modelling

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

    Abstract : Steel fibres are often applied as crack reinforcement in overlays even though methods for the design with respect to crack widths are not yet available. Thus, the intention was for the research to form a basis for future design of overlays with respect to cracks. A main ambition was to give guidance on e.g. READ MORE

  7. 25. 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
