  1. 1. Kritiska vippningslaster för kompositbalkar/lättbalkar av trä

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Jemy Abdalnour; Mohamed Ibrahim Abdirahman; [2023]
    Nyckelord :;

    Sammanfattning : This thesis has focused on the calculation of critical loads for lateral torsional buckling forthree selected wood-based composite beams with varying heights based on the availableMasonite Beams standard range. The main objective has been to investigate and compare ahand calculation model with the recommended method in Eurocode 5, as well as comparethem with results from finite element analysis. LÄS MER

  3. 2. A parametric study of the static and dynamic performance of timber arch footbridges with different hanger configurations

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :ALEJANDRO GARCÍA GARCÍA; [2022]
    Nyckelord :Arch bridges; footbridge dynamics; critical load; bridge typology; parametric study;

    Sammanfattning : The influence of the hanger configuration in the arch and deck bending moments under asymmetric loads is widely used nowadays for improved designs of arch bridges. In this work, by means of a parametric study, those hanger configurations that most efficiently increase both the natural frequencies and buckling factors are identified, simultaneously evaluating the dynamic and static performance of timber arch footbridges.

  4. 3. A comparative evaluation of hydrostatic pressure and buckling of a large cylindrical steel tank designed according to EN14015 and according to the Eurocodes

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

    Författare :Musole Kambita; [2022]
    Nyckelord :Cylindrical steel tanks; yield strength; carbon steel; high strength steel; design load; buckling; stiffening rings; Finite Element Method FEM ; Linear Elastic Bifurcation LBA ; and Geometrically and Materially Nonlinear Analysis with Imperfections GMNIA .;

    Sammanfattning : Above ground steel storage tanks are used worldwide for the storage of various liquids. EN 14015:2005, which has traditionally been used to design the tanks, does not necessarily fulfil the requirements of the Swedish Building Code. LÄS MER

  5. 4. Strength analysis of load-bearingstructures according to Eurocode : Continuous kiln TC

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Simon Söderström; [2021]
    Nyckelord :FEM; Eurocode; stainless steel;

    Sammanfattning : In this work, the load-bearing structure of a wood kiln is analyzed with the finite element method (FEM). The analysis is done with the program Inventor Nastran and consist of a linear stress and buckling analysis. The dimensions of the kiln can vary, therefore reference values are used where it is 32 m long, 12 m high and 10.5 m wide. LÄS MER

  7. 5. Strength assessment of rig foundations for a sailing car carrier

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Alfred Rapaport; [2020]
    Nyckelord :Naval Architecture; Solid Mechanics; Finite Element Analysis; Concept development; Sailing; Skeppsbyggnad; Hållfasthetslära; Finita elementmetoden; Konceptutveckling; Segling;

    Sammanfattning : The wPCC project (wind powered car carrier) is carried out by Wallenius Marine, KTH Royal Institute of Technology and SSPA Sweden. By developing a car carrier mainly propelled by the wind, the emissions are estimated to be reduced by up to 90 %. This thesis deals with the structural aspects of the design. LÄS MER
