1. 1. Finite element analysis of cracking of concrete arch dams due to seasonal temperature variation

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Fredrik Pettersson; Fredrik Hjalmarsson; [2017]
   Keywords : arch dam; hydro power; finite element method; abaqus; temperature variations; concrete; deformation; crack propagation; Technology and Engineering;

   Abstract : 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. READ MORE

3. 2. Verification of the response of a concrete arch dam subjected to seasonal temperature variations

   University essay from KTH/Betongbyggnad

   Author : Oskar Andersson; Max Seppälä; [2015]
   Keywords : Concrete arch dams; thermal effects; ice load; condition monitoring; finite element analysis; Betongvalvdammar; termiska effekter; tillståndsövervakning; islast; finita element analys;

   Abstract : Many dams existing today were constructed around fifty years ago. Condition monitoring is essential for maintaining high safety and determining the current level of safety and stability for these dams. There is a need for new monitoring techniques and finite element coupled monitoring could be one of these techniques. READ MORE
