  1. 1. 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

  3. 2. 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

  4. 3. An alarm system for pore pressure measurements in the foundation ofconcrete dams : a case study of Storfinnforsen buttress dam

    University essay from KTH/Jord- och bergmekanik

    Author : Daniel Falcão de Queiroz; [2018]
    Keywords : Buttress dams; dam foundation; pore pressure; alarm system; alarm limits; sliding in the rock mass; uplift pressure; piezometers.; Lamelldammar; dammgrundläggning; portryck; alarm system; alarmgränser; glidning i bergmassan; upptryck; portrycksmätare;

    Abstract : Concrete buttress dams are relatively light structures and less demandingon foundations; because of that, they may have problems with upliftforces and horizontal joints in the area of the dam´s foundation maypresent a failure mode through sliding. The Storfinnforsen dam, thelargest concrete dam in Sweden, had its foundation studied recently andthe discovery of sub-horizontal joints in the bedrock led to the necessityof having the safety of the dam foundation to sliding assessed.

  5. 4. Prediction of early age and time dependent deformations in a massive concrete structure

    University essay from KTH/Betongbyggnad

    Author : Ali Aghili; Haris Ribac; [2018]
    Keywords : Early age concrete; hydration of cement; Storfinnforsen; ConTeSt; crack risk; temperature development; strain; mass concrete structures; measurement plan; Ung betong; hydratation av cement; Storfinnforsens kraftverk; ConTeSt; sprickrisk; temperatur; töjning; massiva konstruktioner; mätningsplanering;

    Abstract : The heat development that occurs due to the hydration of cement is important to consider during casting of massive concrete structures. By using computer programs that are based on finite element methods (FEM), simulations can be performed on the heat- and strength development. READ MORE

  6. 5. Designing Roller compacted concrete (RCC) dams

    University essay from KTH/Betongbyggnad

    Author : Shayma Al Baghdady; Linnea Khan; [2018]
    Keywords : Roller Compacted concrete; Massive concrete structures; Dams; Concrete;

    Abstract : Concrete is the most common building material in the world and it consists of aggregates,cement and water that harden over time, it is also known as a composite material. The use ofconcrete is very versatile due to its resistance to wind and water and its ability to withstandhigh temperature. READ MORE
