   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

3. 2. 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 naturresurser

   Author : Adamo Jimmy; Abdi Hamse; [2017]
   Keywords : Buckling mode; Matlab script; CUFSM analysis; Half-wavelength; Spring value; Hexagonal; Nonagonal; Dodecagonal;

   Abstract : 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.
