  2. 1. Shear and Torsion in Concrete Structures Non-linear Finte Element Analysis in Design and Assessment

    Author : Helén Broo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; torsion; box-girder bridge; hollow core unit; hollow core floor; non-linear finite element analysis.; shear; prestressed concrete; Reinforced concrete;

    Abstract : For structural design and assessment of reinforced concrete members, non-linear finite element analysis has become an important tool. However, design and assessment of shear and torsion are still done with simplified analytical or empirical design methods. READ MORE

  4. 2. Behaviour and resistance of composite slabs : experiments and finite element analysis

    Author : Milan Veljkovic; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : Composite slab flooring systems are used in steel framed buildings as well as in conjunction with concrete, prestressed concrete and timber structures. Composite slabs consist of a thin-walled profiled steel sheet, reinforcement and in-situ cast concrete. READ MORE

  5. 3. Structural Behaviour of Concrete Railway Sleepers

    Author : Rikard Gustavson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; finite element analysis; three-wire strand; sleeper; bond; strand; pull-through tests; steel encased; push-in tests; bond mechanism; numerical bond model; dynamic loads;

    Abstract : The railway concrete sleeper is an important part of the railway track structure. The sleeper member requires substantial engineering skills during the design and manufacturing process in order to fulfil the requirements set by modern train traffic. READ MORE

  6. 4. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge

    Author : Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anchorage; carbon fibre reinforced polymers; concrete; existing bridges; finite element analysis; flexure; full-scale test; load-carrying capacity; residual prestress force; punching; safety verification; shear; structural assessment; structural behaviour; Structural Engineering; Konstruktionsteknik;

    Abstract : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. READ MORE

  7. 5. Strengthening reinforced concrete structures with FRP composites

    Author : Jincheng Yang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GFRP; finite element analysis.; corrosion; interfacial stress; externally bonded reinforcement; self-anchorage; CFRP; debonding; concrete structures; Fibre reinforced polymer; prestressing level;

    Abstract : Civil infrastructures made of reinforced concrete (RC) play an important role in the economic activities and services of society. However, signs of deterioration and functional deficiency are commonly found in existing RC structures. Thus, there is a great demand for upgrading the capacity and performance of existing concrete structures. READ MORE
