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

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

    Sammanfattning : 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. LÄS MER

  3. 2. Suppressing Torsional Buckling Effects of Angle Members : Application on lattice towers

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och -produktion; Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Savo Yahia Darwish; Richard Skog; [2017]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  4. 3. Resistance of Polygonal Cross Sections of Lattice Wind Tower

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Bicen Jia; [2017]
    Nyckelord :polygonal cross section; wind tower;

    Sammanfattning : Wind energy is one of the most efficient renewable energies. The most used wind towers are tubularand lattice wind towers. Parts of lattice are easier to transfer, especially in the inland areas. Also, it is easier to build higher lattice tower in order to have more efficient energy conversion in inland areas. LÄS MER

  5. 4. Offshore Surveillance of Wave Buoys

    Uppsats för yrkesexamina på avancerad nivå, Elektricitetslära och åskforskning

    Författare :Simon Tyrberg; [2007]
    Nyckelord :;

    Sammanfattning : To gain further knowledge about the motion of the wave buoys involved in the Islandsberg project for wave power, a surveillance system has been designed. The base for the system consists of a lattice tower to be placed on one of two islets southwest of Lysekil: Klammerskären. LÄS MER
