  1. 1. Analysis of a Prefabricated Concrete Skew Angle Slab Bridge

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY); Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Pär Bengtsson; Johan Wallin; [2019]
    Keywords : Finite Element Model; Skew Angle Slabs; Slab Bridge; Prefabrication;

    Abstract : Prefabricated concrete elements are widely used in the construction industry today. With advantages such as time savings, increased safety at the construction site and minimized material usage, prefab becomes a major challenger to the traditional on-site casting construction method.

  2. 2. Cracking in a slender concrete slab due to thermal variation

    University essay from KTH/Betongbyggnad

    Author : Johan Mattsson; Fredrik Åman; [2019]
    Keywords : Concrete slab; Concrete; Finite element analysis; Cracking; Thermal variation; Seasonal temperature; Abaqus; Brigade Plus; Betonggrund; Betong; Finit element analys; Sprickbildning; Termiska laster; Omgivningstemperature; Abaqus; Brigade Plus;

    Abstract : Concrete slabs used in thepulp and paper industries are often situated outdoors, which means that theslabs are exposed to temperature variations due to different weatherconditions. These temperature variations together with operational temperaturesassociated with the manufacturing process, may introduce high temperaturegradients in the concrete. READ MORE

  3. 3. Basic Creep of Young Concrete - Sensitivity in the Evaluation Method

    University essay from KTH/Betongbyggnad; KTH/Betongbyggnad

    Author : Benar Ekmat; Natalea Hermes; [2019]
    Keywords : thermal cracking; young concrete; creep; Linear Logarithmic Model; temperature development; average strain; sensitivity.; Temperatursprickor; ung betong; krypning; Linjär Logaritmisk Modell; temperaturutveckling; töjning; känslighet.;

    Abstract : Creep is defined as deformation that takes place under constant load after an initial elastic response. This thesis focuses on a material property problem area that concerns stress analysis. Focus is on stress development considering creep deformations occurring when a concrete structure is under load, i.e. READ MORE

  4. 4. Parametric Optimization of Foundation Improvements with RC Slabs on Piles

    University essay from KTH/Betongbyggnad; KTH/Betongbyggnad

    Author : Oliver Kling; Nils Dahlman; [2019]
    Keywords : Parametric Design; Parametric Optimization; Concrete Structures; Reinforced Concrete; Foundation Improvements;

    Abstract : Parametric design has proven to be a powerful tool for structural engineers to find innovativesolutions to complex problems more effectively compared to conventional methods. Theflexibility off parametric design is immense since all types of structures depend on a range ofparameters that can be isolated, controlled and altered. READ MORE

  5. 5. The effect of pre-stressing location on punching shear capacity of concrete flat slabs

    University essay from KTH/Betongbyggnad

    Author : Saeed Vosoughian; [2019]
    Keywords : Concrete flat slabs; Concrete damage plasticity model; Eurocode 2; Nonlinear finite element analysis; Punching capacity; Pre-stressing cables;

    Abstract :         Implementing pre-stressing cables is a viable option aiming at controlling deformation and cracking of concrete flat slabs in serviceability limit state. The pre-stressing cables also contribute to punching shear capacity of the slab when they are located in vicinity of the column. READ MORE
