Buckling analysis of a column with rotational springs at both ends in aircraft column

Abstract

In this work, a unified method is proposed for the buckling analysis of a simple supported column with rotational springs at both ends. The displacement is represented by a Fourier sine series. Stokes’ transformation is applied to boundary conditions in order to construct the coefficient matrix of the corresponding systems of linear equations. The derived linear equations can be useful in theoretical investigation that leads to determinant calculation of a 2 × 2 matrix. The present 2 × 2 matrix is more efficient for calculating the buckling loads of the simple supported columns with rotational springs at both ends. © Springer International Publishing Switzerland 2016.
