  1. 1. Chunk Metabolism : Exploring how to plan for reuse of structural elements

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Isabella Nilsson; [2022]
    Nyckelord :Architectural elements; urban metabolism; demolition; deconstruction; design process; structural elements; concrete; steel; circular construction; circular economy; material harvesting; urban mining; Arkitektoniska element; urban metabolism; rivning; dekonstruktion; designprocess; tunga stomelement; betong; stål; cirkulärt byggande; cirkulär ekonomi; material harvesting; urban mining;

    Sammanfattning : With a major share of the negative environmental impacts deriving from construction and its waste, ways to reduce the material and energy use in this sector have been the focus of studies for decades. Reuse of building elements and materials is gaining traction with researchers, architects, developers and real estate owners. LÄS MER

  3. 2. Structural strengthening and sustainability improvements of existing buildings – A case study

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Pardis Niknafs; [2022]
    Nyckelord :Building retrofit; structural strengthening; energy efficiency; environmental impact; integrated and sustainable intervention; cross-laminated timber; life cycle assessment;

    Sammanfattning : In Sweden, a large share of residential buildings was built more than 50 years ago. Consequently, old materials, poor maintenance, and corrosion can affect the structural performance of these buildings. Additionally, these buildings do not meet the latest energy efficiency and Eurocode regulations. LÄS MER

  4. 3. Roof Structure of Bamboo for Solar Panels

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Alfons Hallgren; David Nordmark; [2021]
    Nyckelord :;

    Sammanfattning : Sustainable urbanisation is a pressing challenge in some parts of the world and cost-efficient and environmentally friendly building materials could become a solution to achieve sustainability. Bamboo has shown promising properties in tensile- and bending strength to be able to substitute conventional building materials. LÄS MER

  5. 4. Laboratory testing of shotcrete with fibres of steel, basalt or synthetic materials

    Master-uppsats, KTH/Betongbyggnad

    Författare :Muralidharan Rengarajan; [2020]
    Nyckelord :Fibre reinforced shotcrete; Energy absorption; Residual strength; Fibres; and Laboratory testing;

    Sammanfattning : Shotcrete or sprayed concrete has become an inevitable material for stabilising and supporting hard rock tunnels. To prevent rock block fallouts in the excavated tunnel, shotcrete is pneumatically projected under high pressure on the rock surface. LÄS MER

  7. 5. An experimental study of the validity of the round panel test method for shotcrete

    Master-uppsats, KTH/Betongbyggnad

    Författare :Nadia El zain; [2018]
    Nyckelord :Shotcrete; sprayed concrete; yield line theory; tunnel lining; steel fibers; round determinate panels; test beams; Sprutbetong; runda plattor; tunnelbeklädnad; fiberarmerad sprutbetong; stålfibrer; böjdraghållfasthet; balkar; mätosäkerhet;

    Sammanfattning : Shotcrete (sprayed concrete) was used for the first time in 1914 and has become of  growing importance in stabilizing the excavated tunnel sections over the past century.  Even though the technology develops, there are some difficult tasks such as the design of a bolt anchored tunnel lining made of shotcrete.
