Integral Method for Structural Analysis of Beams with Bending-Torsion Coupling
Journal Title: INCAS BULLETIN - Year 2018, Vol 10, Issue 3
Abstract
This paper deals with structural static or stability analysis of straight beams, when the bending-torsion coupling is considered. A practical case is the lateral buckling analysis of high cross-section beams which involves the coupled bending deflection and twist. Simple rectangular cross-section or thin walled open profile symmetric cross-section beams can buckle laterally when they are subjected to bending with respect to the stiffer plane. Bending-torsion coupling occurs also for some composite beams. The presented approximate integral method uses flexibility influence functions (Green functions) and a matrix formulation, leading to an eigenvalue problem in the case of stability analysis. The formulation can be also used for static or dynamic analysis. Some numerical examples are presented in comparison with the results of other methods.
