  1. 1. Composite timber structures – Ribbed plate design : Evaluation of existing and development of new design methods

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Cristoffer Mård; [2022]
    Nyckelord :Ribbed plates; CLT; gamma-method; Timoshenko-method; shear analogy-method; FE-models; RFEM; Abaqus;

    Sammanfattning : Ribbed plates comprising cross-laminated timber slab, CLT, with glulam beams allow for increased span length compared to pure CLT slabs. At the moment the Eurocodes do not provide any recommendations to design a CLT plate or a ribbed plate. There are handbooks for designing ribbed plates. LÄS MER

  3. 2. Evaluation of a testing method for shear stiffness properties for cross laminated timber

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Calle Lind; [2022]
    Nyckelord :CLT; cross laminated timber; EN 16351; four-point bending; rolling shear modulus; FE-modelling; Technology and Engineering;

    Sammanfattning : Cross laminated timber (CLT) is an engineered wood product that was first developed in the 1990s. Since then it has grown in popularity thanks to its many advantages such as: low environment impact, high degree of prefabrication and low weight. As the material is relatively new the standardization process is still in the early stages. LÄS MER

  4. 3. CHARACTERISATION OF CROSS LAMINATED TIMBER PROPERTIES

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Emil Nilsson; [2021]
    Nyckelord :CLT; cross laminated timber; in-plane loading; out-of-plane loading; beam; rolling shear modulus; experimental tests; FE-modelling; Technology and Engineering;

    Sammanfattning : This project concerns an analysis of a hitherto untested method for determining the modulus of elasticity (MoE) and shear modulus parallel to grain, as well as the rolling shear modulus of cross laminated timber (CLT) through 3-point bending tests. A review of analytical models and methods is included, followed by an evaluation of the effect of the annual ring orientation and shear stress distribution at shear loading of individual board cross-sections.

  5. 4. Spärregler för förlustutjämning vid omstruktureringar av aktiebolag

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakulteten

    Författare :Irina Timoshenko; [2021]
    Nyckelord :skatterätt; handel med underskottsföretag; underskott; beloppsspärr; koncernbidragsspärr; fusionsspärr; fissionsspärr; Law and Political Science;

    Sammanfattning : En av de viktigaste frågorna för bolag gäller möjligheter till förlustutjämning, dvs. kvittning av en förlust som redovisats för ett beskattningsår mot inkomst för ett annat beskattningsår. LÄS MER

  7. 5. Behaviour of cross laminated timber elements with openings at out-of-plane loading conditions

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Christopher Hast; Daniel Fatemi; [2020]
    Nyckelord :CLT; Cross laminated timber; Grillage model; Gamma method; Bernoulli-Euler beam theory; Timoshenko beam theory; Finite element method; FEM; Composite; Abaqus; Technology and Engineering; Science General;

    Sammanfattning : The use of cross laminated timber (CLT) is expanding, its use is relatively new and universal design standards are lacking. One situation for which no universal design standard exists is that of a CLT plate element with an opening. A grillage method has been proposed as a convenient method to design such plate elements.
