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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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.

  4. 8. Digital Twins for Asset Management of Structures

    Författare :Vanessa Saback; Björn Täljsten; Rasmus Rempling; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Twins; BIM; Asset Management; Common Data Environment; Finite Element Modelling; Fiber Optic Sensors; Byggkonstruktion; Structural Engineering;

    Sammanfattning : This thesis deals with asset management of structures through Building Information Modelling (BIM) and Digital Twins.Background: Current inspection and management processes for civil structures are time-consuming and can even be inaccurate. There is an increasingly high potential to improve these processes through recent advances in technology. LÄS MER

  5. 9. FRCM-Composites for Strengthening Concrete Walls with Openings : Experimental and Numerical Analysis

    Författare :Cristian Sabau; Björn Täljsten; Thomas Blanksvärd; Gabriel Sas; Cosmin Popescu; Thanasis C. Triantafillou; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FRCM; reinforced concrete; walls; openings; strenghtening; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Upgrading existing buildings to new functional requirements may require new openings that can weaken the structure, prompting the need for strengthening. In such cases, traditional strengthening solutions, such as creating a reinforced concrete or steel frame around the opening, imply long-term restrictions in the use of the structure. LÄS MER
