  1. 1. 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.

  2. 2. Causality, Magnitude and Impact Mitigation of Rework in Uganda

    Author : John Muhumuza Kakitahi; Byggproduktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rework; Client Quality Requirements; Whole Life Value Philosophy; Public building construction; Uganda;

    Abstract : Research has shown the Ugandan construction industry to be, primarily, an informal sector dominated by unskilled labour contracted mainly on minor building works such as alterations and renovations. Within such a context, the industry has also received negative publicity due to increasing quality failures on sites – commonly referred to as shoddy work. READ MORE

  3. 3. Lean contracting : relational contracting influenced by lean thinking

    Author : Bengt Toolanen; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

    Abstract : The construction sector represents a most vital proportion of Swedish society through its main task of meeting the demands regarding buildings and infrastructure needed, among other things, for living, work, leisure time, education and communication. That this is executed in an effective manner is an important issue for a sustainable development of society. READ MORE

  4. 4. Bracing of steel bridges during construction; theory, full-scale tests and simulations

    Author : Hassan Mehri; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bracing; steel-concrete composite; steel; bridge; test; construction; laboratory; experiment; experimental; theory;

    Abstract : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.

  5. 5. Co-firing complex biomass in a CFB boiler : ash transformation, corrosion control and materials selection

    Author : Henrik Hagman; Dan Boström; Rainer Backman; Mats Lundberg; Lars-Erik Åmand; Umeå universitet; []
    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; ash transformation; process control; equilibrium calculations; boiler availability; failures; alloy selection; alloy degradation; vortex finder VF ; service life estimation; sulfation; chloridation; high temperature corrosion; biomass; waste derived fuels; forest residues; RDF; Biomal; slaughterhouse waste; peat; waste wood; industrial waste water treatment sludge; HAD; RSMT; Alloy 253MA; Alloy 310S; Alloy 800H HT; Alloy DS; Alloy 600;

    Abstract : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.
