FEM Modelling of Lateral-Torsional Buckling using Shell and Solid Elements
MetadataShow full item record
The paper describes two methods of FEM modelling of I-section beams loaded by bending moments. Series of random realizations with initial imperfections following the first eigenmode of lateral-torsional buckling were created. Two independent FEM software products were used for analyses of resistance. At the end the difference and correlation between the results as well as advantages and disadvantages of both methods are discussed. (C) 2017 Published by Elsevier Ltd.
