  1. 1. Strengthening of concrete structures by the use of mineral based composites

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Thomas Blanksvärd; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Strengthening of concrete structures with epoxy bonded carbon fiber reinforced polymers (CFRP) has been proved to be an excellent strengthening technique. However, using epoxy adhesives for bonding do contain some disadvantages such as diffusion closeness, thermal incompatibility to the base concrete, regulations regarding the working environment and minimum application temperature.

  2. 2. Strengthening of concrete structures by the use of mineral based composites system and design models for flexure and shear

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Thomas Blanksvärd; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : A great number of society's resources are invested in existing concrete structures, such as bridges, tunnels, different kind of buildings etc. All of these structures have both an expected function and an expected life span. However, both the function and the life span can be influenced by external factors, e.g. LÄS MER

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

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Cosmin Popescu; Björn Täljsten; Gabriel Sas; Thomas Blanksvärd; Stijn Matthys; [2017]
    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. 4. FRCM-Composites for Strengthening Concrete Walls with Openings Experimental and Numerical Analysis

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Cristian Sabau; Björn Täljsten; Thomas Blanksvärd; Gabriel Sas; Cosmin Popescu; Thanasis C. Triantafillou; [2018]
    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
