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

    Master-uppsats, KTH/Betongbyggnad

    Författare :Sofia Thuresson; [2020]
    Nyckelord :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.;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Betongbyggnad; KTH/Betongbyggnad

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Betongbyggnad

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

    Sammanfattning :         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. LÄS MER

  4. 4. Utmattning vid svetsad anslutning mellan tväravstyvning och fläns i samverkansbro

    Kandidat-uppsats, KTH/Byggteknik och design; KTH/Byggteknik och design

    Författare :Daniel Lindman; Jonas Berlin Lindberg; [2019]
    Nyckelord :Fatigue crack; composite bridge; Hot spot method; FEM; parameter control; Eurocode; web stiffener; Utmattningsspricka; samverkansbro; Hot spot-metoden; FEM; parameterstyrning; Eurokod; livavstyvning;

    Sammanfattning : Vid samverkansbroar fästes tvärförband mellan huvudbalkar med funktion att leda laster ut mot huvudbalkarna. Dessa kan fästas via s.k. livavstyvningsplåtar mot huvudbalkens liv samt flänsar. LÄS MER

  5. 5. Optimization Workflow for Flat Slab Systems : Using Parametric Design with Visual programming

    Master-uppsats, KTH/Mekanik; KTH/Mekanik

    Författare :Klas Lindstrand; Axel Simonsson; [2018]
    Nyckelord :;

    Sammanfattning : The advancement of IT and technology has enabled the development of boundary breaking tools such as Parametric design and visual programming. Structural engineering has the potential to take the advantage of this development, by implementing visual programming which with the combination of optimization algorithms can explore design proposals.
