  2. 1. "What are your intentions?" - On Ship Bridge Decision Making

    Author : Robert Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; human factors; Navigation in fairway; decision making;

    Abstract : AbstractThis thesis discusses central aspects of decision making on a Ship Bridge in its natural context with focus on the task of navigating in fairway. The background springs from the fast development of instruments related to work on the ship bridge. If not implemented and used correctly new technology may even contribute to accidents. READ MORE

  4. 2. Autonomous bridge inspection based on a generated digital model

    Author : Ali Mirzazade; Björn Täljsten; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggkonstruktion; Structural Engineering;

    Abstract : Railway owners manage geographically dispersed networks comprising major elements of ageing infrastructure that are very susceptible to natural hazards. Consequently, transport agencies must address maintenance issues to guarantee serviceability and safety. READ MORE

  5. 3. Towards Sustainable Construction: Life Cycle Assessment of Railway Bridges

    Author : Guangli Du; Raid Karoumi; Håkan Sundquist; Helge Brattebo; KTH; []
    Keywords : Life cycle assessment; LCA; Environment; Railway Bridge; Sustainability; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Abstract : Since last few decades, the increased pressure from the environmental issues of natural resource depletion, global warming and air pollution have posed a great challenge worldwide. Among all the industrial fields, bridge infrastructures and their belonged construction sector contribute to a wide range of energy and raw materials consumptions, which is responsible for the most significant pollutions.

  6. 4. Application of Fracture Mechanics to Concrete Bridges. Finite element analyses and experiments

    Author : Mario Plos; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforced concrete; reinforcement splice; full-scale test; shear failure; fracture mechanics; fatigue test; static test; concrete frame corner; non-linear finite element analysis; concrete bridge;

    Abstract : Material models based on fracture mechanics together with non-linear finite element analyses have been used in combination with experiments to study the behaviour of reinforced concrete bridges. The work covers two aspects of interest in the design of concrete bridges.* The shear behaviour was studied in full-scale tests on two highway bridges. READ MORE

  7. 5. Holistic approach in engineering design - controlling risks from accidental hazards in bridge design

    Author : Ivar Björnsson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; codes; accidental; extreme; bridges; holistic; approach; robustness; risk; reliability; uncertainty;

    Abstract : Engineering design, in concise terms, is what engineers do using what they know. It is the underlying decision making activity that determines what is to be built and how it should be built. An ever present requirement in engineering design is that the structure should be safe.
