    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D concrete printing; digital fabrication; concrete structures; additive manufacturing; robotic fabrication; design for manufacturing; structural optimisation; functionally graded concrete; topology optimisation.; 3D-betongutskrift; digital tillverkning; betongkonstruktioner; additiv tillverkning; robotstyrd tillverkning; design för tillverkning; strukturell optimering; funktionellt graderad betong; topologioptimering.; Betongbyggnad; Concrete Structures;

    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. Toward Realistic Failure Evaluations for Concrete Buttress Dams

    Author : Jonas Enzell; Anders Ansell; Erik Nordström; Andreas Sjölander; Richard Malm; Leif Lia; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete dams; buttress dams; stability analysis; dam failure behavior; physical model tests; FEM; betongdammar; lamelldammar; stabilitetsanalys; dammbrott; fysiska modellförsök; FEM; Betongbyggnad; Concrete Structures;

    Abstract : Concrete dams, complex structures supporting massive loads, have traditionally been assessed using simplified 2D analytical stability analyses based on the rigid body assumption. Previous studies have shown that 3D behavior, such as the interaction between the monoliths and the valley's geology, can greatly impact the load-bearing capacity of gravity dams but remains largely unexplored in buttress dams.

  5. 3. Anchorage of naturally-corroded, plain bars in Reinforced Concrete structures

    Author : Samanta Robuschi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bond; corrosion; concrete; anchorage; plain reinforcement bars;

    Abstract : Reinforced Concrete (RC) is the most common construction material in existing structures. However, RC structures are susceptible to deterioration over time, with corrosion of the reinforcing steel as most common mechanism. Corrosion reduces strength and ductility provided by the reinforcement bars and affects their interaction with the concrete. READ MORE

  6. 4. Structural Effects of Reinforcement Corrosion in Concrete Structures

    Author : Mohammad Tahershamsi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experiments; load-carrying capacity; anchorage; pitting; FE analysis; natural corrosion; Bond properties; damage assessment; modelling.; structural behaviour; reinforced concrete structures; 3D optical scanning; inspection;

    Abstract : Reinforcement corrosion is a common cause of deterioration in reinforced concrete.The corrosion mechanism involved and the consequent structural behaviour ofdeteriorated reinforced concrete members have been studied by several researchers. READ MORE

  7. 5. Buildability of concrete structures : processes, methods and material

    Author : Peter Simonsson; Peter F. Court; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The causes for the slow development of the construction industry is often attributed the traditional ”peculiarities of construction“, including such factors as one-of-a-kind products, temporary organisation, and on-site production. However, signs of new thinking are becoming apparent in the construction industry in Sweden that emphasise change. READ MORE
