  1. 1. 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

  3. 2. Glued connection for TCC slabs : Experimental and Numerical investigation

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

    Författare :Ervin Halilovic; Seid Lotinac; [2022]
    Nyckelord :TCC connection; Composite element; Adhesive connection; Silicone Adhesive; Polyurethane Adhesive; Slip modulus; Shear stress; Cohesive elements; Traction seperation law; Mullins effect; Hysteresis;

    Sammanfattning : Timber-concrete composite (TCC) structures are becoming more popular in several industrial applications as an efficient method for optimizing the structural performance and the cost of construction as well as lowering the emissions of carbon dioxide. TCC floors are more sustainable than pure concrete floors and more resistant to vibrations and excessive deflections than pure wooden floors. LÄS MER

  4. 3. Cryoballoon Catheters with sensors for treatment of AF

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Axel Anderberg; [2021]
    Nyckelord :Atrial fibrillation; balloon; catheter; cryoablation; flexible electronics; Ballong; flexibel elektronik; förmaksflimmer; kateter; kryoablation;

    Sammanfattning : Atrial fibrillation is a cardiac condition in which the heart rate is abnormally fast and/or irregular. While not yet proven to be fatal on its own, it severely increases the probability of developing further medical conditions including a five times higher risk of getting stroke. LÄS MER

  5. 4. Industrial Requirements for Cross-Laminated Timber Manufacturing

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Författare :Matilda Torneport; [2021]
    Nyckelord :Cross-laminated timber; CLT industry; Wood species; Adhesive; Strength class; Timber grades;

    Sammanfattning : Wood is a valuable sustainable material that meets the requirements for structural application. Cross-laminated timber (CLT) is a wood-based product that is mainly used in the building industry. Due to the rapid global market increase, a number of new CLT plants are emerging worldwide and thereby a need for standardisation is more than ever. LÄS MER

  7. 5. Från tejp till tyg : en studie om hur processer utvecklatsför att tillverka tyg av reflextejp

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Fanny Anonsen; Göran Jansson; [2020]
    Nyckelord :reflective tape; multilayer yarn; polymeric materials; shredding; twisting; heat fixation; reflextejp; flerskiktsgarn; polymera material; strimling; tvinning; värmefixering.;

    Sammanfattning : Denna rapport beskriver arbetet med att konstruera utrustning för att strimla, tvinna och fixera en flerskiktsfilm i form av reflextejp med avsikten att tillverka garn av den strimlade tejpen där garnet slutligen stickas och vävs till tyger. Avsikten är inte att utveckla reflexgarn eftersom existerande metoder finns för detta, utan att undersöka om garntillverkning från filmmaterial, eller i en förlängning, andra tvådimensionella material lämpar sig för garnproduktion.
