1. 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 naturresurserAbstract : 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

2. Resistance of Polygonal Cross Sections of Lattice Wind Tower
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : 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. Behavior of polygonal semi-closed thin-walled cross-section : A study based on finite strip analysis
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : The acceptance and the use of cold-formed steel sections has significantly increased in recent years due to advantages such as consistency and accuracy of profile, ease of fabrication, high strength and stiffness to the lightness in the weight. For thin-walled columns, made by folding a plane plate into a section, it is possible that when they are subjected to compression loads they may buckle either locally, if the member is very short, or globally if the member is very long.
