1. Numerical study of the effect of thermal ice loads on concrete dams
University essay from KTH/BetongbyggnadAbstract : It is essential to understand the mechanics of ice load and how it affects concrete dams located in a cold climate, such as Sweden, where the temperature becomes sufficiently cold to freeze the surface of the reservoir. The purpose of this thesis is to study ice load distribution along concrete dams, and its response during the application of an ice load. READ MORE

2. Behavior prediction of concrete dams
University essay from KTH/BetongbyggnadAbstract : As many dams were built around 1950, the expected life span of these dams are about tobe reached. With this, the need for monitoring and increased understanding of the damsstructural integrity increases. In order to prevent failures, two warning signals are defined;alert and alarm. READ MORE

3. Thermal cracking of a concrete arch dam due to seasonal temperature variations
University essay from KTH/BetongbyggnadAbstract : 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. READ MORE

4. Finite element analysis of cracking of concrete arch dams due to seasonal temperature variation
University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaperAbstract : 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

5. Verification of the response of a concrete arch dam subjected to seasonal temperature variations
University essay from KTH/BetongbyggnadAbstract : 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
