  1. 1. 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.

  3. 2. Stålförstärkning av limträbalkar för att öka hållfasthet och styvhet

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Fredrik Lindahl; Mateusz Kjellkvist; [2014]
    Nyckelord :limträ; balkar; förstärkning; hållfasthet; styvhet; stål; linjärelastisk modell; provning; Technology and Engineering;

    Sammanfattning : In today’s housing market, open house plans are requested increasingly. This puts a demand on the beams being used to manage longer spans and is therefore exposed to larger loads. To manage these larger loads, one solution is to increase the beam dimensions. LÄS MER

  4. 3. Train-Bridge Interaction on Freight Railway Lines

    Uppsats för yrkesexamina på avancerad nivå, KTH/Bro- och stålbyggnad

    Författare :Davide Martino; [2011]
    Nyckelord :train-bridge interaction; dynamics; acceleration; freight train models; track models;

    Sammanfattning : This study investigates the dynamic response of a railway bridge under train passage. Three load models designed around the Swedish Steel Arrow freight train are tested and compared. A series of Concentrated Forces, a succession of single degree of freedom Sprung-Masses, and a sequence of complex multi-degree of freedom Train Wagons. LÄS MER

  5. 4. Optimum Design and Analysis of a Composite Drive Shaft for an Automobile

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Författare :Sanjay Gummadi; Akula Jagdeesh Kumar; [2007]
    Nyckelord :Torque transmission; Torsional buckling capacities; Fundamental lateral Natural frequency; Bernoulli Euler theory; Timoshenko beam theory; Static analysis; Modal analysis; Buckling analysis; Ansys.;

    Sammanfattning : Substituting composite structures for conventional metallic structures has many advantages because of higher specific stiffness and strength of composite materials. This work deals with the replacement of conventional two-piece steel drive shafts with a single-piece e-glass/ epoxy, high strength carbon/epoxy and high modulus carbon/epoxy composite drive shaft for an automotive application.
