Key words: Buckling, Finite Element Analysis (FEA), horizontal side load, elastic buckling. 1. Introduction. Various sources are available in the field of elastic stability theory that derive the equations necessary for determining the critical buckling load of a beam or column while under axial loading [1,2,3], or torsion loading [4].
attempts are summarised by Massonnet [1] and that an exhaustive review of the theory of beam-columns is due to Chen and Atsuta [2]. The background is also developed in the successive issues of the guide produced by the. Structural Stability Research Council (formerly the Column Research Councii) [3]. Those who want
equation of beam-column theory and we present the analytical expression of the deflection equation for different boundary conditions. Then we present the Euler buckling load for q(x) = 0. Next we present the formulation of the fourth order non-homogeneous beam- column equation using both Finite Difference method and.
The work of a column is simpler than the work of a beam. • The loads applied to a column are only axial loads. • Loads on columns are typically applied at the ends of the member, producing axial compressive stresses. • However, on occasion the loads acting on a column can include axial forces, transverse forces, and
BEAM COLUMNS. 7.1 Introduction. The Indian steel code is now in the process of revision as specification-based design gives way to performance-based design. An expert committee mainly comprising eminent academics from IIT Madras, Anna University Chennai, SERC Madras and. INSDAG Kolkata was constituted to

Beam-column design involves consideration of the combined effects of axial load and flexure, usually in the form of an interaction equation, or rather inequality, compared to a limiting value. The first design standards were based on allowable (or working) stress design (ASD or WSD) theory. In ASD, stresses in the structure
Eulers Theory : The struts which fail by buckling can be analyzed by Eulers theory.The cornerstone of column theory is the Euler column, a mathematically straight, prismatic. The Euler load, PE, is a reference value to which the strengths of. Euler-Bernoulli Beam Theory: Displacement, strain, and. Beam theory assumptions
