    Abstract : Today’s buildings are responsible for 40% of the world’s energy use and also a substantial share of the Global Warming Potential (GWP). In Sweden, about 21% of the energy use can be related to the heat losses through the climatic envelope. READ MORE

  5. 5. Restraint Effects in Concrete Bridges : A Study of Cracking due to Thermal Actions and Shrinkage in Portal Frame Bridges

    Author : Erik Gottsäter; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tvång; Betong; Uppsprickning; Temperaturlast; Plattrambro; FE-analys; Restraint; Concrete; Cracking; Thermal action; Portal frame bridge; FE-analysis;

    Abstract : Thermal actions and shrinkage cause volume changes in concrete structures. In structures which are restrained from movements, the restraint effects can cause cracking. However, when cracking occurs, the structure can deform to some extent, which reduces the restraint stresses and thus also the crack widths. READ MORE
