  2. 1. Shear in Concrete Structural Elements Subjected to Dynamic Loads

    Author : Johan Magnusson; Anders Ansell; Mikael Hallgren; Richard Malm; Jaap Weerheijm; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic load; initial response; shear failure; shear capacity; numerical simulations; bond; shear span; support reactions; Dynamisk last; initial respons; skjuvbrott; skjuvkapacitet; numeriska simuleringar; förankring; skjuvspännvidd; upplagsreaktioner; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Concrete structural elements subjected to severe dynamic loads such as explosions at close range may cause shear failures. In the Oklahoma City bombing in 1995 two concrete columns on the ground level were reported to have failed in shear. READ MORE

  4. 2. Implementation and Application of Fracture Mechanics Models for Concrete Structures

    Author : Magnus Åkesson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bond slip; concrete cracking; abstract data types; prestressing; enhanced strain;

    Abstract : Two numerical models for simulation of concrete cracking and bond slip have been implemented and applied in various comparative analyses. Both models were implemented in the commercial finite element system ABAQUS. READ MORE

  5. 3. Structural Retrofitting of Reinforced Concrete Beams using Carbon Fibre Reinforced Polymer

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

    Abstract : This thesis details experimental work and finite element simulations of reinforced concrete beams retrofitted with carbon fibre reinforced polymer (CFRP). The objectives of this study were to investigate the behaviour of retrofitted beams experimentally, develop a finite element model describing the beams, verifying the finite element model against the experimental results and finally investigating the influence of different parameters on the behaviour of the retrofitted beams.

  6. 4. 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

  7. 5. Models for analysis of shotcrete on rock exposed to blasting

    Author : Lamis Ahmed; Anders Ansell; Erik Nordström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shotcrete; Rock; Vibration; Stress waves; Numerical analysis.; Sprutbetong; Berg; Vibrationer; Spänningsvågor; Numerisk analys.;

    Abstract : In underground construction and tunnelling, the strive for a more time-efficient construction process naturally focuses on the possibilities of reducing the times of waiting between stages of construction. The ability to project shotcrete (sprayed concrete) on a rock surface at an early stage after blasting is vital to the safety during construction and function of e. READ MORE
