  2. 1. Moderate Nominalism and Moderate Realism

    Author : Christer Svennerlind; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; analytic ontology; moderate nominalism; moderate realism; particular; universal; abstract; concrete; abstract particular; abstract universal; concrete particular; concrete universal; trope; moment; complex unity; collection; instance; unit attribute; intensional aspect; predicational aspect; continuous composite; articulated composite;

    Abstract : The subject matter of this thesis is analytic ontology. Chapters II and III deal with two versions of trope theory, or moderate nominalism; these are defined as ontologies which recognise properties and relations but no (real) universals. The key notion of both theories, trope, is characterised as an abstract particular. READ MORE

  4. 2. Design for 3D Concrete Printing : Optimisation Through Integrated Workflows

    Author : Jose Hernández Vargas; Johan Silfwerbrand; Helena Westerlind; Roberto Naboni; KTH; []
    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

  5. 3. On Mesoscale Modelling of Coupled Chloride-Moisture Transport in Concrete

    Author : Filip Nilenius; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coupled diffusion; concrete; moisture; mesoscale; chloride ions.; Multiscale modelling; computational homogenization;

    Abstract : The service life behaviour of concrete structures is highly influenced by the ingress of chloride ions. At sufficiently high concentrations, chloride ions can initiate corrosion of embedded reinforcement bars, which may substantially reduce the structure's bearing capacity and ultimately lead to structural collapse.

  6. 4. Multiscale Modelling of Reinforced Concrete

    Author : Adam Sciegaj; 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; multiscale; bond-slip; cracking; computational homogenisation; reinforced concrete;

    Abstract : Since concrete cracks at relatively low tensile stresses, the durability of reinforced concrete structures is highly influenced by its brittle nature. Cracks open up for ingress of harmful substances, e.g. chlorides, which in turn cause corrosion of the reinforcement. READ MORE

  7. 5. Multiphysical analysis methods to predict the ageing and durability of concrete

    Author : Tobias Gasch; Anders Ansell; Richard Malm; Erik Nordström; Max Hendriks; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ageing; Cracking; Creep; Concrete; Durability; Finite Element Method; Multiphysics; Shrinkage; Beständighet; Betong; Finita elementmetoden; Krypning; Krympning; Multifysik; Sprickbildning; Åldring; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : With the societal demand for sustainability and the increasing age of infrastructure, a crucial task for the civil engineering community is to improve the durability of concrete structures. This thesis aims to contribute to such development through theoretical studies using mathematical modelling and numerical simulations. READ MORE
