  1. 6. Förband i korslimmade träkonstruktioner : Kraftöverföring mellan KL-träskivor och optimering av antal förbindare i bjälklagskivor

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Daniella Issaki; Gabriel Icho; [2022]
    Nyckelord :Joints; CLT-wood; transverse force; Eurokod 5; connection; Förband; KL-trä; tvärkraft; Eurokod 5; anslutning;

    Sammanfattning : Behovet av att snabbt kunna leverera klimatanpassade, högkvalitativa och kostnadseffektiva byggnader gör trämaterialet till ett självklart alternativ inom byggbranschen. Utvecklingen av korslimmat träskivor (KL-trä), orsakar att materialet är ett vanligt förkommande byggmaterial inom byggbranschen. LÄS MER

  3. 7. Classification of ultrasonic signals using machine learning to identify optimal frequency for elongation control : Threaded fastening tools

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Mazen Bahy; [2022]
    Nyckelord :Machine Learning; Convolutions Neural Network CNN ; Barker signals; Ultrasonic sensors; Clamp-force; Threaded fastening assembly; Maskininlärning; konvolutionellt neuralt nätverk; Barker-signaler; Ultraljudssensorer; klämkraft; Åtdragningsmontering;

    Sammanfattning : Studying the preload in a screw joint has been the focus of today’s industry. The manufacturer reflects that demand by investigating different opportunities and techniques to develop this area. There are four different ways of controlling the tightening of bolts and joints to achieve the required clamp force that can hold for a specific preload. LÄS MER

  4. 8. Screw Joint Analysis in Radio Frequency Filters

    Master-uppsats, KTH/Industriell produktion

    Författare :Nils Löwhagen; [2022]
    Nyckelord :Digital filter; Pre-load force; Clamp torque; Release torque; Surface roughness; Thermal shock test; Digitalt filter; Förspänningskraft; Klämvridmoment; Lossdragningsmoment; Ytjämnhet; Termiskt chocktest;

    Sammanfattning : Filter devices are central elements of radio units utilized for modern-day telecommunication. Leakages of radio waves and passive intermodulation are evolving more prominent as the frequency bands become crowded. LÄS MER

  5. 9. Strength of axially loaded screw joints in wooden structures exposed to fire : An overview of existing knowledge and proposal for test method

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Emma Wiklund; [2021]
    Nyckelord :Fire; Wood; Screws; Strength; test method;

    Sammanfattning : Today, distinct approaches are required when designing timber structures and their joints in the event of fire. Considering that the steel fasteners have temperature dependent properties and that the surrounding wooden construction is also affected by the fire due to occurrence of charring during fire exposure, these types of joints are complicated to design.

  7. 10. Performance of joints for glued laminated timber exposed to the ISO fire temperature curve

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Jesus Gil; [2021]
    Nyckelord :Glued laminated Timber; Structural fire engineering; Fire performance; standard ISO fire curve; Joints; Technology and Engineering;

    Sammanfattning : As society becomes more ecologically conscious there is a push toward the use of materials with a smaller environmental burden, one of these materials is glulam (GLT), which has gained a lot of traction in recent years not only for ecological reasons but for its ease in manufacture, transport, noise dampening, etc. The focus of this project was to evaluate the influence of different joint configurations on the fire performance of glulam members.
