  1. 1. 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

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

    University essay from KTH/Betongbyggnad

    Author : Brook 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

  4. 3. Techno-Economic Analysis of an Innovative Purely Solar Driven Combined Cycle System based on Packed Bed TES Technology

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Tianqi Ruan; [2019]
    Keywords : Tower CSP Techno-economic analysis; Dynamic simulation; Tower CSP teknisk-ekonomisk analys; Dynamisk simulering;

    Abstract : With increasing awareness of environmental issues and worldwide requirements for sustainable development, renewable energy technologies with lower environmental impact, especially those having abundant resources like wind and solar energy, attract more attention. Concentrating Solar Power (CSP) is one of the most promising solar energy technologies. READ MORE

  5. 4. Finite Element Modelling and Parametric Studies of Semi-Closed Thin-Walled Steel Polygonal Columns - Application on Steel Lattice Towers for Wind Turbines

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Bona Ryan; [2017]
    Keywords : Lattice tower; Thin-walled element; Semi-closed polygonal section; Finite element analysis; Parametric study; Buckling; Python script; Matlab script; Eurocode 3; Factorial design;

    Abstract : The trend of structural engineering in the recent years is toward the use of lighter and moreeconomical structural elements. In steel construction, peculiarly, thin-walled structural elements arebecoming more popular and have a growing importance. READ MORE

  6. 5. Suppressing Torsional Buckling Effects of Angle Members : Application on lattice towers

    University essay from Luleå tekniska universitet/Byggkonstruktion och -produktion; Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Savo Yahia Darwish; Richard Skog; [2017]
    Keywords : ;

    Abstract : Wind towers are a today under a global development and many countries put more focus on this environmentally friendly way of producing electricity. The performance requirement increase and at the same time the wind towers should be economical. READ MORE
