  1. 1. CFD Analyses for Wind Load AssessmentCFD Analyses for Wind Load Assessment : Wind-induced vibrations in the Bomarsunds Bridge hangers

    University essay from KTH/Bro- och stålbyggnad

    Author : Fatiha El Azrak; [2023]
    Keywords : ;

    Abstract : The trend in recent years of building longer and slender bridge components has introduced new challenges to ensure their stability and strength. This master thesis focuses on the effects of wind-induced vibrations in the context of long, slender arch bridge components, particularly the recently constructed Bomarsunds Bridge in Åland, Finland.

  3. 2. Utilisation of hardwood in cross-laminated timber - A numerical study on vibrations in floors

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Johannes Jonasson; Olle Karlsson; [2022]
    Keywords : hardwood; birch; beech; clt; cross-laminated timber; vibrations; floors; footfall; accelerations; Technology and Engineering;

    Abstract : Cross-laminated timber (CLT) is an engineered wood product consisting of several layers of laminations bonded together with adhesives. In contrast to heavier construction materials, timber and other lightweight building materials are more prone to serviceability issues due to vibrations. READ MORE

  6. 5. Dynamic Performance of a Tall Building to Earthquake Loading : Finding the optimum mass and stiffness

    University essay from KTH/Bro- och stålbyggnad

    Author : Andrés Alonso San Segundo; [2022]
    Keywords : ;

    Abstract : With the increasing cost of land, the development of ultra-high performance concrete, and the technological advancements in equipment and machinery, we are able to construct and refurbish skyscrapers like never before. How they are built, what materials they use, or what structural system defines them, all affect their dynamic response, which in the end is the combination of the stiffness and mass, two key parameters in engineering of tall buildings.
