  1. 1. Parametric optimization of reinforced concrete slabs subjected to punching shear

    University essay from KTH/Betongbyggnad

    Author : Sofia Thuresson; [2020]
    Keywords : Parametric design; Optimization; Punching shear; Concrete; Flat slab; Eurocode 2; Shear reinforcement; Genetic algorithm; Visual programming; Dynamo.; Parametrisk design; Optimering; Genomstansning; Betong; Pelardäck; Eurocode 2; Tvärkraftsarmering; Genetisk algoritm; Visuell programmering; Dynamo.;

    Abstract : The construction industry is currently developing and evolving towards more automated and optimized processes in the project design phase. One reason for this development is that computational power is becoming a more precise and accessible tool and its applications are multiplying daily. READ MORE

  3. 2. Punching shear in concrete flat slabs supported on slender edge steel columns

    University essay from KTH/Betongbyggnad

    Author : Pasha Jalal; Jose Andres Perez; [2020]
    Keywords : Punching shear; ATENA; FEA; precast slab; flat slab; top and foot plate.; Genomstansning; ATENA; FEA; plattbärlag; pelardäck; topp- och fotplåt.;

    Abstract : Punching shear is a failure mechanism caused by concentrated loads, creating a crack pattern that resembles a cone shape or piece of pie starting from the top surface of the slab and prolongs downwards. When the total shear force is greater than the shear resistance of the slab, it may eventually lead to punching shear failure. READ MORE

  4. 3. 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

  5. 4. Comparison of Punching Shear Design Provisions for Flat Slabs

    University essay from KTH/Betongbyggnad

    Author : Jonatan Aalto; Elisabeth Neuman; [2017]
    Keywords : Punching shear; resistance; concrete; flat slab; design provisions; Eurocode 2; case study; parametric study; shear reinforcement; prestressed;

    Abstract : Abstract A new generation of EN 1992-1-1 (2004) also known as Eurocode 2 is under development and currently there is a set of proposed provisions regarding section 6.4 about punching shear, PT1prEN 1992-1-1(2017). It was of interest to compare the proposal with the current punching shear design provisions. READ MORE

  6. 5. Non-Linear Assessment of a Concrete Bridge Slab Loaded to Failure

    University essay from KTH/Betongbyggnad

    Author : Eriksson Isabell; Niklas Karlsson; [2016]
    Keywords : concrete; linear shear; punching shear; non-linear finite element analysis; Eurocode; Model Code; ATENA 3D; betong; skjuvning; genomstansning; icke-linjär finit-elementanalys; Eurocode; Model Code; ATENA 3D;

    Abstract : This thesis covers an investigation regarding the failure in the bridge slab of Gruvvägsbron, which was the result of the full scale test that the bridge was subjected to prior to demolition. Using the non-linear finite element software ATENA 3D, a model of the bridge was assembled, with the purpose to attempt to reenact the test procedure and realistically capture the failure load and behaviour.
