1. 6. Assessing the safety of cracked concrete dams

   University essay from KTH/Betongbyggnad

   Author : Abdelsamad Mohamed Osman Fadul; [2021]
   Keywords : Buttress dams; Concrete; Global stability; Design criteria; RIDAS; Sliding; Overturning; Finite element analysis; Progressive failure analysis;

   Abstract : AbstractThe overall safety of dams depend on several stipulations. One of them is global stability of the dam, which is addressed with approaches like that in (RIDAS, 2017) (the Swedish power companies’ guidelines for dam safety). When designing a new dam, two global failure modes; sliding and overturning should be considered according to RIDAS. READ MORE

3. 7. Influence of Foundation Modelling on the Seismic Response of a Concrete Dam

   University essay from KTH/Betongbyggnad

   Author : Stella Harrison; Siri Nöjd; [2021]
   Keywords : concrete dam; earthquake; finite element analysis; free-field forces; mass foundation; betong dam; jordbävning; finita element analys; free-field forces; inkluderad bergsmassa;

   Abstract : It is of great importance to ensure the structural safety of dams during earthquakes since a failure may cause catastrophic consequences. Conventional computation of the structural response of dams is based on a simplified approach where the foundation is considered as massless. READ MORE

4. 8. Numerical study of the effect of thermal ice loads on concrete dams

   University essay from KTH/Betongbyggnad

   Author : Imal Zuwak; Wasseem Kordoghly; [2020]
   Keywords : Arch dam; Buttress dam; Concrete; Finite element analysis; Ice load; Valvdamm; Lamelldamm; Betong; Finit elementanalys; Islast;

   Abstract : 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

5. 9. Behavior prediction of concrete dams

   University essay from KTH/Betongbyggnad

   Author : Isak Nilsson; Leonard Sandström; [2020]
   Keywords : Concrete dams; dam monitoring; dam safety; measurement evaluation; databased models i;

   Abstract : 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

6. 10. Design of RCC gravity dam and FEM modelling in GeoStudio - Longtan dam

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Patrick Lucas Arkadiusz Bochnak; Maria Eugenia Correa Saracco; [2020]
   Keywords : RCC; China; Longtan dam; Flood routing; GeoStudio; Technology and Engineering;

   Abstract : China’s rapid economic development has led to a continuously increasing energy demand and the country is the world’s biggest energy user as of today. The country accounts for around 23% of the global energy production, but 70% of the Chinese energy is generated with coal power and China is the biggest emitter of CO2 in the world. READ MORE
