  1. 1. Life cycle analysis and comparison of climate impact for two alternative floor systems for increased weight in high-rise timber buildings

    University essay from KTH/Byggnadsmaterial

    Author : Nir Kedem; [2022]
    Keywords : Life cycle assessment; LCA; Anavitor; Environmental impact; Building materials; Timber; Concrete; Gravel; Adding weight system.;

    Abstract : The aim of this Master Thesis is to investigate and quantify the climate impact for two floor system alternatives for the Cederhusen project, that is the 8 floors timber-based buildings located at Sankt Eriksplan in Stockholm. The overall motivation for this study is the fact that the construction industry is a major contributor to the total amount of the global greenhouse gas emissions. READ MORE

  3. 2. Long-term deformation of balanced cantilever bridges due to non-uniform creep and shrinkage

    University essay from KTH/Betongbyggnad

    Author : Sidra Akbar; Mathias Carlie; [2021]
    Keywords : Balanced cantilever bridges; box girder cross-section; concrete; non-uniform creep and shrinkage; Bažant’s B4 model; Eurocode 2; long-term deformations; finite element analysis; Freivorbau broar; lådtvärsnitt; betong; ojämnkrypningoch krympning; BažantsB4 modell; Eurokod 2; långtidsdeformationer; finita element analys;

    Abstract : Balanced cantilever bridges have historically experienced excessive deformations. Previous researchsuggeststhat the cause may be due to differential thickness in the box girder cross-section and underestimation of creep and shrinkage. READ MORE

  4. 3. Carbonation of concrete : Evaluation of CO2 uptake of Benders Sverige AB concrete products and landfills

    University essay from

    Author : Juliana Kessler; Joakim Melander; Emil Tronde; Gustav Åderman; Erik Österlund; [2021]
    Keywords : ;

    Abstract : The cement industry accounts for 5-7% of the global emissions of carbon dioxide, where CO2 is mainly emitted during the calcination process. However, CO2 is also absorbed by all concrete products during their lifetime through the process of carbonation. READ MORE

    Keywords : Additive Manufacturing; Construction; Robotics; Machine Design; Heavy Industry; Technology and Engineering;

    Abstract : Increased popularity of additive manufacturing has pushed the method into new areas where it has not been used before, such as construction. Buildings are being 3D printed by various companies around the world, but the application of additive manufacturing in construction is still in its early stages. READ MORE

  6. 5. Investigation of impact sound behaviour in light weight floor constructions - A market survey and finite element analysis

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Fanny Sandberg; [2016]
    Keywords : intermediate floor; acoustics; impact sound; höga trähus; bjälklag; akustik; Stegljud; Ljud; wood; wooden high rise building; Technology and Engineering;

    Abstract : In the last years, the interest in high-rise timber framed building has gone up resulting in an increased demand for good solutions regarding sound insulation. Due to the worldwide growing interest in environmental issues, it has become of greater importance for companies to find ways to take care of their residue, instead of throwing it away. READ MORE
