  1. 11. Safety Assessment of Cracked Buttress Dams

    University essay from KTH/Betongbyggnad

    Author : Robel Tekeste Fekadu; Sujata Kayastha; [2020]
    Keywords : Concrete buttress dam; finite element analysis; safety factor; global failure; reinforcement; corrosion; combined failure; traditional stability analysis;

    Abstract : Most of the concrete buttress dams in Sweden were built from the 1950s till the1980s based on the traditional method of analyses. Those structures are reinforced and heavy in structure. Their height to thickness ratio being large makes them prone to crack during their lifespan. READ MORE

  3. 12. Probabilistic non-linear finite element analysis of concrete buttress dams

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Adrian Ulfberg; [2019]
    Keywords : ATENA; FREET; SARA; probabilistic; numerical; Kalhovd; FEA; FEM;

    Abstract : Assessment of concrete buttress dams today consists of using analytical methods to investigate the stability in different failure modes. However, they simplify the problem at hand and neglect certain important features linked to geometry and thus not truthfully appraise the structures real stability. READ MORE

  4. 13. Alternative methods to prevent thermal cracking in concrete

    University essay from

    Author : Alexander Barchin; Navid Sedighi; [2019]
    Keywords : Massive concrete structures; heat development; cement hydration; temperature reduction; cracking; fly ash; ice; coarse aggregates; cooling methods; practical tests.; Massiva betongkonstruktioner; värmeutveckling; cementhydrataion; temperaturreducering; sprickbildning; flygaska; is; grov ballast; kylningsmetoder praktiska försök.;

    Abstract : In the construction industry, concrete is the most common material, because of its good properties such as compressive strength and endurance. Concrete is a composition of several different materials where one of the main components is cement. When the hydration process starts, large amount of heat is generated. READ MORE

  5. 14. 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.
