  2. 1. Plate bonding : strengthening of existing concrete structures with epoxy bonded plates of steel or fibre reinforced plastics

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

    Abstract : This thesis deals with several aspects of the plate bonding problem, i.e. when steel or fibre reinforced plastics (FRP) plates are bonded to a concrete structure with the use of an epoxy adhesive. Both theoretical work and laboratory tests are presented as well as a full scale test on a strengthened concrete bridge. READ MORE

  4. 2. 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 : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  5. 3. Autonomous bridge inspection based on a generated digital model

    Author : Ali Mirzazade; Björn Täljsten; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggkonstruktion; Structural Engineering;

    Abstract : Railway owners manage geographically dispersed networks comprising major elements of ageing infrastructure that are very susceptible to natural hazards. Consequently, transport agencies must address maintenance issues to guarantee serviceability and safety. READ MORE

  6. 4. Use of Macro Basalt Fibre Concrete for Marine Applications

    Author : Ali Mohammadi Mohaghegh; Johan L. Silfwerbrand; Vemund Årskog; Anniken T.Karlsen; Björn Täljsten; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Concrete Barges; Reinforcement Corrosion; Floating Structures; Macro Basalt Fibres; Self-Compacting Fiber Concrete; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Deterioration of concrete structures due to the corrosion of embedded steel is a well-known universal problem. Norway with its numerous bridges, ports, offshore and floating structures along its coastline, is also encountered with corrosion degradation. READ MORE

  7. 5. CFRP Strengthening of Cut-Out Openings in Concrete Walls – Analysis and Laboratory Tests

    Author : Cosmin Popescu; Björn Täljsten; Gabriel Sas; Thomas Blanksvärd; Stijn Matthys; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Redesigning buildings to improve their space efficiency and allow changes in use is often essential during their service lives to comply with shifts in living standards and functional demands.This may require the introduction of new openings in elements such as beams, walls, and slabs,which inevitably reduces their structural performance and hence requires repair or strengthening.
