  1. 11. Simulation of load capacity of 3D printed concrete patterns

    University essay from KTH/Betongbyggnad

    Author : Magnus Burton; Karolina Näsén; [2022]
    Keywords : ;

    Abstract : Three-dimensional concrete printing (3DCP) is a technology which has rapidly developed in recent years. The technology is based on a layer-by-layer technique where models are designed in a 3D software program and printed by a robot. Unlike conventional concrete, 3DCP has stricter material requirements due to the absence of formwork. READ MORE

  2. 12. Numerical method to investigate and assess the capacity of a damaged concrete structure : Using image analysis and advanced concrete modeling

    University essay from KTH/Bro- och stålbyggnad

    Author : Zakariya Benosmane; [2022]
    Keywords : Damaged Concrete Structure; Extended Finite Element Method XFEM ; Concrete Dam- aged Plasticity CDP ; Photogrammetry; Crack Detection Methods.;

    Abstract : Concrete has for decades been one of the main materials used to construct important structuressuch as dams and bridges. However, after years of service, the concrete structuresstart deteriorating and signs of damages start showing on the structure. READ MORE

  3. 13. Low-carbon concretes in infrastructures : Applicability, potential and carbon footprint focusing on the Parisian Metro Line L18

    University essay from KTH/Betongbyggnad

    Author : Romain Durand; [2022]
    Keywords : ;

    Abstract : Low-carbon concretes are more and more commonly used to limit the environmental impact of concrete structures. Among concrete structures, infrastructures are characterized by their high load-bearing function (foundations, bridges, aqueducts, dams, etc.). READ MORE

  4. 14. Strengthening of non-composite bridges by Partial Composite Action

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

    Author : Johan Tjernberg; [2022]
    Keywords : Composite action; Composite bridges; Partial shear connection; Partial Composite Action; Shear connectors; Coiled Spring Pins;

    Abstract : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

  5. 15. Influence of load distribution on trough bridges

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

    Author : Jacob Gustafsson; [2021]
    Keywords : Bridge; Trough bridge; Concrete; Load distribution; Ballast;

    Abstract : There are approximately 4000 railway bridges in Sweden and a common construction type is the short span concrete trough bridge. With the current standards the load distribution through ballast is assumed to be uniformly distributed with a distribution slope of 2:1 according to the Swedish Administration of Transport or 4:1 according to Eurocode 1.
