  1. 11. Resistance of Polygonal Cross Sections of Lattice Wind Tower

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

    Author : Bicen Jia; [2017]
    Keywords : polygonal cross section; wind tower;

    Abstract : 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. READ MORE

  3. 12. Wind-induced vibrations in high-rise buildings

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

    Author : Fredrik Steffen; [2016]
    Keywords : wind; high-rise; tall buildings; ritz-vectors; dynamic analysis; Technology and Engineering;

    Abstract : Buildings are getting taller due to increased urbanisation and densification of cities. More advanced construction methods and the desire to construct impressive buildings is also supporting the trend. READ MORE

  4. 13. Environmental and economic analysis of renewable energy producing systems with a focus on wooden towers as components of wind-solar systems -The Dali PowerTower case study

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Anca Stoica; [2014]
    Keywords : Earth and Environmental Sciences;

    Abstract : This paper aims at assessing the economic features and the environmental impact of a wooden tower used in wind-solar renewable energy generating systems. The life cycle assessment method and return on investment method were used in order to achieve the objectives of the study. READ MORE

  5. 14. COMPARISON STUDY FOR WIND RESOURCE ASSESMENT IN COMPLEX DOMAIN USING METEODYN AND WINDSIM

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Carlos Díaz-Asensio Mancebo; [2014]
    Keywords : Wind; Resource; Assessment; Windsim; Meteodyn; Embankment; Hjardemål;

    Abstract : Two commercial Computational Fluid Dynamic (CFD) wind resource assessment tools namely Meteodyn WT and Windsim have been compared for an embankment site named Hjardemål. For comparison of both software, a controlled experiment is carried out for a fixed set-up with same domain size and same number of cells in the X, Y and Z directions. READ MORE

  6. 15. Modal Testing and Structural Identification

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

    Author : Tobias Kristensson; [2014]
    Keywords : Modal testing; Modal analysis; Structural identification; Vibration; Signal; EMA; OMA; Technology and Engineering;

    Abstract : Bridges have been built around the world for at least 3000 years and have made it possible for man to travel over obstacles like valleys and rivers, which has contributed to the rapidly growing infrastructure we have today. Efforts made to save materials and reduce production costs have led to lighter and slender structures, which in turn can cause dynamic problems where the bridge is sensitive to vibrations. READ MORE
