2. 1. Timber Pile-Supported Embankments : Arching and Reinforcement

   Author : Per Gunnvard; Jan Laue; Hans Mattsson; Qi Jia; Luc Thorel; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timber piles; piled embankment; geosynthetic reinforcement; geosynthetic-reinforced pile-supported embankment; arching; finite element method; full-scale test; Geoteknik; Soil Mechanics;

   Abstract : Reduced climate impact is a worldwide strive today. The foundation engineering industry is continuously searching for more sustainable solutions to reduce resource usage and pollutions directly or indirectly. One such solution is timber piling, as an alternative to the commonly used concrete and steel piles. READ MORE

4. 2. Reinforcement in Tailor-made Concrete Structures

   Author : David Fall; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailor-made concrete structures; Steel fibre reinforcement; Automated production; Geometrically complex structures; Reinforcement alternatives;

   Abstract : In tailor-made concrete structures of complex geometries, the formability of concrete is an asset. To use this formability in load-bearing structures, the concrete needs to be reinforced. During the past century steel bars were used; however, in recent decades, alternative reinforcement methods have been introduced. READ MORE

5. 3. Steel Fibres in Reinforced Concrete Structures of Complex Shapes: Structural Behaviour and Design Perspectives

   Author : David Fall; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometrically complex structures; Steel fibre reinforcement; Concrete structures; Reinforcement alternatives; Rational design;

   Abstract : In concrete structures of complex geometries, the formability of concrete is an asset.However, complex geometries introduce time-demanding form and reinforcement works. READ MORE

6. 4. Steel members strengthened with carbon fibre reinforced polymers - A study of local and global structural behaviour

   Author : Dag Linghoff; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement; CFRP laminate; adhesive; design;

   Abstract : Investigations have been conducted by several research groups to study the effect of using carbon fibre reinforced polymers (CFRP) as reinforcement on steel beams and a brief summary of this work is given in this thesis. Laboratory studies of reinforced steel beams demonstrate that the bending stiffness and the ultimate load-carrying capacity can be significantly increased. READ MORE

7. 5. Chloride initiated reinforcement corrosion in marine concrete

   Author : Paul Sandberg; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; w c ratio; cover thickness; chloride penetration; service life prediction; corrosion cells; chloride thresholds; field exposure tests; marine concrete; pozzolans; reinforcement corrosion; chloride binding; Building construction; Byggnadsteknik;

   Abstract : Factors affecting the total chloride threshold for initiation of pitting corrosion in reinforced concrete were investigated by means of field and laboratory exposure tests. Factors affecting the chloride penetration into concrete were also investigated by means of field tests. The thesis consists of a summary (86 p.) and 11 papers attached. READ MORE
