    Sammanfattning : To define art is no easy task. Quotes such as ”Art is the elimination of the unnecessary” and ”A picture is worth a thousand words”, implies that art has something to do with conveying information. This is compatible with the fact that instructions are often conveyed in the form of images instead of text. LÄS MER

  3. 2. Designing Roller compacted concrete (RCC) dams

    Master-uppsats, KTH/Betongbyggnad

    Författare :Shayma Al Baghdady; Linnea Khan; [2018]
    Nyckelord :Roller Compacted concrete; Massive concrete structures; Dams; Concrete;

    Sammanfattning : Concrete is the most common building material in the world and it consists of aggregates,cement and water that harden over time, it is also known as a composite material. The use ofconcrete is very versatile due to its resistance to wind and water and its ability to withstandhigh temperature. LÄS MER

  4. 3. Thermal cracking of a concrete arch dam due to seasonal temperature variations

    Master-uppsats, KTH/Betongbyggnad

    Författare :Jonas Enzell; Markus Tollsten; [2017]
    Nyckelord :Arch dam; Concrete; Finite element analysis; Cracking; Progressive failure analysis; Valvdamm; Betong; Finit elementanalys; Sprickor; Progressiv brottanalys;

    Sammanfattning : Concrete dams located in northern regions are exposed to large seasonal temperature variations. These seasonal temperature variations have resulted in cracking in thin concrete dams. Continuous monitoring and evaluation of existing dams are important to increase the knowledge about massive concrete structures and to ensure dam safety. LÄS MER

  5. 4. Moisture-induced crack development in timber beams : a parametric study performed on dowelled timber connections

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

    Författare :Tadios Sisay Habite; [2017]
    Nyckelord :Moisture; Crack; Extended finite element; Parametric study;

    Sammanfattning : A problem has been observed by many researchers regarding the cracks caused mainly by moisture variation in timber structures. However, this effect has been neglected over the past decades. LÄS MER
