3. 12. Steel fibre reinforced concrete toppings exposed to shrinkage and temperature deformations

   Författare :Jonas Carlswärd; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : The work presented in the thesis primarily focuses on problems that are characteristic for thin layers of concrete exposed to imposed loads. More specific, the work aims at investigating, or rather finding ways to evaluate the efficiency of steel fibres as regards the limitation of crack widths in concrete under restrained conditions.

4. 13. Structural Retrofitting of Reinforced Concrete Beams using Carbon Fibre Reinforced Polymer

   Författare :Yasmeen Obaidat; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : 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.

5. 14. Fibres in reinforced concrete structures - analysis, experiments and design

   Författare :Anette M Jansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crack width; stress crack-width relationship; design methods; post cracking; analysis method; Fibre-reinforced concrete;

   Sammanfattning : Potential benefits from fibres in concrete are improved crack control and the possibility of more slender structures. The extent of the crack control depends, among other factors, on the amount of fibres added, and plays a great role for durability. LÄS MER

7. 15. Carbon fibre reinforced polymers for strengthening of structural elements

   Författare :Anders Carolin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : There is a large need for strengthening of concrete structures all around the world. There can be many reasons for strengthening, increased loads, design and construction faults, change of structural system, and so on. The need exists for both strengthening in flexure as well as in shear. LÄS MER
