  1. 1. Feasibility study of a high-rise CLT building in a seismic area with high wind loads : A finite element approach

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Inga Berglind Eggertsdóttir; Emelía Ósk Gunnarsdóttir; [2023]
    Nyckelord :;

    Sammanfattning : Timber has been used as a construction material for thousands of years. However,the inventions of stronger materials and increased construction of taller buildings hasled to decreased use of wood products. LÄS MER

  3. 2. Dynamisk analys av en gång och cykel fackverksbro av trä

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Ture Zingmark; August Claesson; [2022]
    Nyckelord :;

    Sammanfattning : The interest in increasing the use of timber in structural engineering has risen significantly inrecent years due to the urgency of reducing the environmental impact of the building industry.Timber bridges is one of the many possible use-cases for timber in structural engineering.

  4. 3. 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

  5. 4. Development of Methodology for Finite Element Simulation of Overhead Guard Impact Test

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Axel Hallén; Jacob Hjorth; [2022]
    Nyckelord :Explicit Finite Element Analysis; Forklift Overhead Guard; RADIOSS; Drop Test; Strain-Rate Sensitivity; Johnson-Cook; Plasticity; Explicit finita elementanalys; Skyddstak; Gaffeltruck; RADIOSS; Fallprov; Töjningshastighetsberoende; Johnson-Cook; Plasticitet;

    Sammanfattning : Forklifts that are capable of lifting heavy loads and reaching high lift heights are required by stan-dards to have an overhead guard to protect the operator from falling objects. The same standardsspecify a standardized procedure for testing the strength of these overhead guards. LÄS MER

  7. 5. Korslimmat trä i flerbostadshus - En kostnads och klimatjämförelse med betong i byggskedet

    Master-uppsats, Lunds universitet/Byggproduktion

    Författare :Mattias Lindkvist; Oscar Wallin; [2022]
    Nyckelord :Korslimmat trä; KL-trä; betong; stommaterial; byggkostnad; klimatpåverkan; livscykelanalys; Technology and Engineering;

    Sammanfattning : Purpose: The purpose of the study is to investigate the cost and climate impact of apartment blocks, built with cross laminated timber. In the study, a comparison is made with concrete, which is the most common frame material. The purpose of the study is to increase awareness of opportunities and challenges for apartment buildings in timber. LÄS MER
