  1. 16. Numerical simulations of shear reinforced concrete beams subjected to blast loads

    Master-uppsats, KTH/Betongbyggnad

    Författare :Anton Frank; Andreas Fristedt; [2021]
    Nyckelord :Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

    Sammanfattning : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.

  3. 17. Modelling masonry spires : An investigation

    Master-uppsats, KTH/Betongbyggnad

    Författare :Dennis Lillemo; [2021]
    Nyckelord :Abaqus; Concrete damage plasticity; Finite element method; Limit analysis; Macro-modelling; Masonry; Masonry spire; Nonlinear material; Salisbury Cathedral; Abaqus; Concrete damage plasticity; Finita elementmetoden; Gränsanalys; Makromodellering; Murverk; Murad tornspira; Icke-linjärt material; Katedralen i Salisbury;

    Sammanfattning : Masonry spires are a typical part of church architecture. Since it is rare that masonry is used as a load-bearing material in the western world today, it is important to maintain and increase the knowledge of modelling masonry structures both from a maintenance point of view and to build new masonry structures.

  4. 18. Stretchable Barrier Coatings For Fiber-Based Materials : A laboratory study into the development of extensible/stretchable barrier coatings with nanoclay implementation, focusing on water vapour barrier properties.

    Master-uppsats, Karlstads universitet

    Författare :Kajin Muradparist; [2021]
    Nyckelord :Stretchable; Barrier; Coating; WVTR; WVP; Hydroforming; Töjbar; Barriär; Bestrykning; WVTR; WVP; Hydroforming;

    Sammanfattning : Executive summary Today, packaging has gained a significant role in the food industry as well as other industries. Paper substrates that have been coated in some ways are typically used to make packaging. The amount and type of pigment used in the formulation determine whether this coating is a pigment coating or a barrier coating. LÄS MER

  5. 19. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis

    Master-uppsats, KTH/Betongbyggnad

    Författare :Mohammad Mustafa Angar; [2020]
    Nyckelord :Pile cap; Nonlinear finite element analysis; ATENA 3D; Reinforcement layout; Strut and tie method; Pålfundament; icke-linjära finita elementmodeller; strut and tie-metoden;

    Sammanfattning : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. LÄS MER

  7. 20. Grundförstärkning med pålar i berg : I befintlig konstruktion med begränsat utrymme

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Madicken Höglund; Marcus Larsson; [2020]
    Nyckelord :Steel pipe; steel core pile; waterproofing; pile foundation; down-the-hole DTH drill.;

    Sammanfattning : This study has been done in order to examine which type of pile, pile driving- and waterproofing methodsare most suited for an existing building. A building that will undergo an extensive reinforcement of itsfoundation. LÄS MER
