  1. 1. 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.

  2. 2. The Wake Effect and Wind Farm Clustering

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Igor Ciric; [2021]
    Keywords : wake effect impact; wake mitigation measures; farm to farm wakes; Southern Middle Bank; wind farm clustering; Technology and Engineering;

    Abstract : The wind energy industry is growing rapidly and as offshore wind expands in the Baltic sea, more and more clusters will be observed. The purpose of this work is to better understand the impact that wakes have on the electricity production for wind farm clusters in the Southern Middle Bank region. READ MORE

  3. 3. Telescopic Tower Facilitating Installation of ≥12 MW Offshore Wind Turbines

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Martin Pettersson; [2020]
    Keywords : Installation of Offshore Wind Turbines; Telescopic Tower; Pin and Hole Jacking System; Friction Connection; Installation av vindkraftverk till havs; teleskopisk torn; hydraulisk jacksystem; friktionskoppling;

    Abstract : The trend of offshore wind power is bigger and bigger wind turbines. Turbines are now becoming so big that existing installation vessels no longer are feasible and new bigger installation vessels are needed. READ MORE

  4. 4. Estimating the Risk of Self-Initiated Upward Lightning to Onshore Wind Turbines and Towers

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Frida Thörn; Wilhelm Sjöstedt; [2020]
    Keywords : Lightning; upward lightning; self-initiated light-ning; wind turbines; modelling;

    Abstract : Field observations has shown that wind turbinesare especially exposed to lightning strikes. The probability forlightning strikes to offshore wind turbines has been analysed ina previous article. In this project the probability for upwardself-initiated lightning strikes to onshore wind turbines anda lightning protection tower was analysed. READ MORE

  5. 5. Effects of cracking of coupling beams onhigh rise towers subjected to wind load

    University essay from KTH/Betongbyggnad

    Author : Biruk Worku Woldemikael; [2020]
    Keywords : Crack; reinforcement content; aspect ratio; shear deformation; joint flexibility; concrete grade; effective stiffness.; Sprickor; förstärkningsinnehåll; tvärsnittsförhållande; skjuvdeformation; ledflexibilitet; betongkvalitet; effektiv styvhet;

    Abstract : In high rise towers, reinforced concrete elevator shafts with coupling beams are extensively used as a principal structural element to resist lateral loads. The lateral load resistance of the tower is dominantly dependent on the stiffness of the load-bearing walls, and coupling beams connecting them. READ MORE
