  1. 1. Experimental Investigation of Net-Tension Capacity in Birch Plywood Gusset Plates via Mechanical Connectors and Adhesives

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Ibrahim Abd Ullah Alhamo; Farid Mobin; [2023]
    Nyckelord :;

    Sammanfattning : This thesis examines the mechanical behavior and performance of plywood connections withmechanical connectors and adhesive bonding to glulam. The aim is to provide insights into thecapacity and characteristics of these connections for well-founded design decisions in timberstructures. LÄS MER

  3. 2. Utredning och test av olika jordtryckskoefficienter med hänsyn till fraktionsstorlekar på stödkonstruktioner

    M1-uppsats, Jönköping University/Tekniska Högskolan

    Författare :Alexander Johansson; Herman Hallgren; [2022]
    Nyckelord :Eurocode; Experimental test; Angle of internal friction; Geo-construction; Earth pressure; earth pressure coefficient; Classical earth pressure theory; The Swedish Transport Administration.; Eurocode; Experimentellt test; Friktionsvinkel; Geokonstruktion; Jordtryck; Jordtryckskoefficient; Klassisk jordtrycks teori; Trafikverket;

    Sammanfattning : Introduktion – En fråga har väckts kring hur jordtryck beräknas enligt en klassiskjordtryckteori som beskrivs i läroböcker så som (Sällfors,2009), Trafikverket krav och Eurocode av företaget Vara byggkonsult AB. För att skapa en bättre förståelse så togett praktiskt test fram för att mäta jordtrycket utifrån klassiska teorier och jämförs med dessa. LÄS MER

  4. 3. Moment-resisting connections for glulam using birch plywood : An experimental study on both mechanical and adhesive connections

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Jonatan Ringaby; [2022]
    Nyckelord :;

    Sammanfattning : The aim of this study was to investigate the load-bearing capacity and stiffness of mechanical and adhesively bonded connections in timber structures with gusset plates made of birch plywood, as a preliminary study for potential future use in long-span timber structures which could reduce the environmental impact of the building sector by substituting steel with wood products in moment-resisting connections. Birch plywood was chosen for this study due to its high bending strength in comparison to plywood made of softwoods and its availability on the market. LÄS MER

  5. 4. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Axel Barrdahl; [2022]
    Nyckelord :Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

    Sammanfattning : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. LÄS MER

  7. 5. Load-bearing wood connections using birch plywood : An experimental study of birch plywood gusset plates behaviour with mechanical connectors

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Mattia Debertolis; Agne Laurinaviciute; [2022]
    Nyckelord :;

    Sammanfattning : A growing sustainability concern is pushing the construction industry to seekalternative materials with lower environmental impact. In the last decade useof wood as load-bearing construction has become a common trend, however,connections of timber elements are still performed by the use of steel plates. LÄS MER
