  1. 1. Semi-Automatic calculation of the stability of shear walls in multi-storey buildings

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Erik Bolin; Emil Sjöstedt; [2022]
    Keywords : Horizontal stabilisation; Dynamo; Shear walls; Stability; Conceptual design phase; Visual programming; Openings in shear walls; Load distribution; Relative stiffness; Technology and Engineering;

    Abstract : Performing horizontal stability analysis in the conceptual design phase is time consuming and adjustments in the geometry of the building require new time consuming calculations. Often buildings are modelled in 3D modelling software such as Revit and Tekla but the calculations are often performed in a separate software. READ MORE

  3. 2. 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

  4. 3. 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. 4. 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

  6. 5. 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
