  1. 1. Use of Digital Image Correlation for monitoring of concrete buttress dam failure model tests

    University essay from KTH/Betongbyggnad

    Author : Jarl Jensen; Markus Leijström; [2022]
    Keywords : ;

    Abstract : The monitoring of dam structures is of great importance for the safety of the dam.A dam failure can cause disastrous consequences for people and infrastructure downstream.Dams are monitored by periodic inspections and monitoring systems. READ MORE

  3. 2. Numerical method to investigate and assess the capacity of a damaged concrete structure : Using image analysis and advanced concrete modeling

    University essay from KTH/Bro- och stålbyggnad

    Author : Zakariya Benosmane; [2022]
    Keywords : Damaged Concrete Structure; Extended Finite Element Method XFEM ; Concrete Dam- aged Plasticity CDP ; Photogrammetry; Crack Detection Methods.;

    Abstract : Concrete has for decades been one of the main materials used to construct important structuressuch as dams and bridges. However, after years of service, the concrete structuresstart deteriorating and signs of damages start showing on the structure. READ MORE

  4. 3. Numerical simulations of pore pressure on concrete buttress dams

    University essay from KTH/Betongbyggnad

    Author : Mohammed Abdi; Dimitirios Ntzimanis; [2022]
    Keywords : Porepressureanalysis; upliftpressure; buttressdams; drainage; groutcur- tain; rockfractures; damsafety; RIDAS.;

    Abstract : Uplift pressure is one of the most dominant forces on a dam structure. Difference in head water and tail water creates a hydraulic gradient resulting an upward oriented pressure called uplift pressure, which reduces the dam safety against sliding. READ MORE

  5. 4. 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

  6. 5. 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
