- Abstract
A matrix displacement method of analysis is described which can account for the non-linear flexural, axial and torsional behaviour of elastic thin-walled I-section beams and beam-columns. The non-linear analysis is achieved by subdividing the beams and beam-columns into submembers and then accounting for the translation and rotation of these submembers in the analysis. The method is initially applied to a uniform simply supported beam with equal end moments for which an accuracy study is carried out. The method is then applied to a stepped beam and a propped cantilever to demonstrate its capacity to handle more complex boundary conditions. The concise formulation of the method allows a simple understanding of the elastic nonlinear structural behaviour of thin-walled beams and beam-columns. The method has been designed for extension to non-doubly symmetric sections and complete frames.
