Finite element analysis of cracking of concrete arch dams due to seasonal temperature variation
Flera dammkonstruktioner i Norden utsätts för stora temperaturvariationer mellan sommar och vinter. I norra Sverige kan dammar vara utsatta för temperaturvariationer på upp emot 60–70 °C. Detta resulterar ofta i sprickbildning i betongen vilket medför utmaningar vid både utformning av nya dammar och underhåll av befintliga. Säsongmässiga temperaturvariationer är den dominerande orsaken till spricDams located in the Nordic countries are subjected to large temperature variations between summer and winter. In the northern part of Sweden dams are subjected to temperature variations of up to 60-70 °C. This often results in cracking of the concrete and causes challenges in the design of new dams as well as maintenance of existing dams. Seasonal temperature variation has been found to be the do
