Buckling Analysis of Straight Beams with different Boundary Conditions using an Integral Formulation of corresponding Differential Equations
Journal Title: INCAS BULLETIN - Year 2018, Vol 10, Issue 4
Abstract
This work deals with structural stability analysis of straight beams, having different boundary conditions. The particular case of the beam on elastic foundation is also analyzed. The method of analysis is an approximate integral one, using structural flexibility functions (Green’s functions). The differential equations governing the Euler buckling of such beams are put in integral form. This approach is a matrix one leading to an eigenvalues problem in the case of stability analysis. Different numerical examples concerning the calculation of the critical buckling loads are presented in comparison with available data from literature. The obtained results show good agreement from engineering point of view.
