   Abstract : The transition from conventional cast concrete to 3D Concrete Printing (3DCP) marks a paradigm shift by directly depositing fresh concrete layer upon layer according to a digital model without the need for a formwork. This technology offers the possibility of achieving innovative and complex geometries in an automated process. READ MORE

4. 2. Rotation capacity of reinforced high strength concrete beams

5. 3. Design of concrete pavements : design criteria for plain and lean concrete

   Author : Johan Söderqvist; Johan Silfwerbrand; Anders Lenngren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

   Abstract : New road infrastructure projects are important and constitute of large investments that have to serve the society for a long time. The investments have to be durable at the lowest life cycle cost and the pavements have to sustain loads from increasing traffic intensity and heavy traffic loads. READ MORE

6. 4. FRP shear strengthening of reinforced concrete beams

   Author : Gabriel Sas; Giorgio Monti; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber reinforced polymers; shear; reinforced concrete; strengthening; model; comparison; literature review; Structural Engineering; Konstruktionsteknik;

   Abstract : The shear failure mechanisms of flexural reinforced concrete (RC) members is highly complex; its precise details cannot be explained with simple analytical relationships, and are the topic of considerable scientific debate. The studies described and examined the three most used shear theories in the world – the fixed angle truss model (45°TM), the variable angle truss model (VAT), and modified compression field theory (MCFT).

7. 5. Structural Behaviour of Deteriorated Concrete Structures

   Author : Kamyab Zandi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FE analysis; concrete; stirrup; corrosion; bond; pull-out test; frost;

   Abstract : A growing concern for better assessment of existing concrete structures has revealed a need for improved understanding of the structural effects of deterioration. The two most common causes of deterioration in concrete structures are freezing of the concrete and corrosion of the reinforcement. READ MORE
