  1. 1. Prestress and its application to shell, fabric, and cable net structures

    Author : Alexander Sehlström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; HUMANIORA; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; HUMANITIES; Structuraldesign; Prestress; Architecture; Engineering; Stress pattern; Conceptual design; Form finding; Geometric stiffness;

    Abstract : Prestressing and shells provide means to create material-efficient and well-functioning structures, as do their combination, offering opportunities for increased material efficiency within the built environment. Prestressing introduces stresses in an object to enhance its performance, and shells include concrete shells, masonry vaults, fabric structures, cable nets, and timber or steel gridshells.

  2. 2. Prestress in Nature and Technics

    Author : Alexander Sehlström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; HUMANIORA; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; HUMANITIES; Geometrical stiffness; Prestress; Form finding; Architecture; Structural design; Stress pattern; Engineering; Conceptual design;

    Abstract : To direct the forces of nature is a central task in the creation of spaces and load-carrying structures for architecture. This research investigates how prestress can be used as a design tool for the creation of material efficient and well-functioning structures, and in early design stages contribute to sustainable, functional and beautiful architecture.

  3. 3. Computational Methods in Conceptual Structural Design

    Author : Vedad Alic; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; conceptual design; conceptual structural design; ground-borne vibrations; form finding; optimization; dynamic relaxation; graphic statics; reciprocal figures; strut-and-tie; finite element method; isogeometric analysis; NURBS; CAD; numerical modelling;

    Abstract : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. READ MORE

  4. 4. Geometry linking the art of building and the Universe: Geometric patterns on shells and grid shells

    Author : Emil Adiels; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; HUMANIORA; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; HUMANITIES; Form finding; Differential Geometry; Conceptual design; Geometry; Shell; Engineering; Masonry; Craftsmanship; Grid shell; Architecture; Structural design;

    Abstract : Geometry links the art of building and the physics of space-time. Mathematical breakthroughs in geometry have led to new ways of designing our structures and our ability to visualise and describe the world, phenomena in nature and the universe. READ MORE

  5. 5. Stiffness and vibration properties of slender tensegrity structures

    Author : Seif Dalil Safaei; Gunnar Tibert; René Motro; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tensegrity booms; Tensegrity grids; Tensegrity power lines; Finite element analysis; Genetic algorithm; Flexibility analysis; Form-finding; Pre-stress design; Optimization;

    Abstract : The stiffness and frequency properties of tensegrity structures are functions of the pre-stress, topology, configuration, and axial stiffness of the elements. The tensegrity structures considered are tensegrity booms, tensegrity grids, and tensegrity power lines.A study has been carried out on the pre-stress design. READ MORE
