Abstract: Fully intrinsic equations are used to obtain a model compliant with Euler-Bernoulli assumptions for a beam under a linearly distributed follower force known as a Hauger column. The advantage of the intrinsic formulation in modeling problems with non-conservative forces is discussed here. Only intrinsic parameters which are independent of the choice of coordinate system has been used and four different boundary conditions were implemented. Also, a comparison between the present study and similar studies with the classical formulation has been developed. The Generalized Differential Quadrature Method is used to numerically analyze the critical load of the beam. It is well understood that there is a remarkable advantage in terms of convergence using intrinsic equations in comparison with the classical formulation.
