  1. 1. Industrial Bridge Engineering -Structural developments for more efficient bridge construction

    Författare :Peter Harryson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; product and productivity developments; materials developments; Keywords: Bridges; fibre-reinforced polymers.; industrial construction process; steel-fibre-reinforced ultra-high-performance concrete; design; structural joints; structural developments;

    Sammanfattning : In recent years, growing concern about the deficiencies and lack of efficiency in the construction industry has highlighted the need of research in order to make substantial improvements, rectify incongruities and succeed in progressive development. For bridges, the advantages that can be expected from an industrial construction process are especially interesting. LÄS MER

  2. 2. Sustainability-, Buildability- and Performance-driven Structural Design

    Författare :Alexandre Mathern; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; HUMANIORA; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; HUMANITIES; material developments; performance; requirements; constructability; sustainability; buildability; integrated design; structural engineering; structural developments; design method; bridges; finite element analysis; concrete structures; civil engineering; construction technology;

    Sammanfattning : The construction, maintenance and operation of infrastructure networks represent substantial impacts, both positive and negative, in all three dimensions of sustainability: economic, social and environmental. The greatest possibility to reduce the negative impacts and increase the positive ones is at the early design stage of construction projects. LÄS MER

  3. 3. Structural studies of small viruses using an X-ray Free Electron Laser

    Författare :Anna Munke; Marvin Seibert; Dirk Hasse; Inger Andersson; Carl Caleman; Maria Selmer; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Sammanfattning : X-ray crystallography has since its introduction been the most successful technique for solving protein structures. Viruses however, often possess structural components such as fibrils, tails and envelopes that make them difficult or impossible to crystallize. LÄS MER

  4. 4. Structural Identification of Civil Engineering Structures

    Författare :Tarek Edrees; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The assumptions encountered during the analysis and design of civil engineering structures lead to a difference in the structural behavior between calculations based models and real structures. Moreover, the recent approach in civil engineering nowadays is to rely on the performance-based design approaches, which give more importance for durability, serviceability limit states, and maintenance.
