For eccentrically loaded the short columns behavior will follow the linear path until intersect the interaction diagram. In the limit of studied columns when increasing slenderness ratio from short column condition to slenderness ratio of. Short columns short columns fail by crushing at very high stress levels that are above the elastic limit of the column material. Like classical column buckling theory, the buckling of columns under eccentric offset loads is also a topic of unique complexity. The main studied parameters were eccentricity of the applied load, column slenderness ratio. The design of eccentrically loaded columns using the strain compatibility method of analysis described requires that a trial column be selected.
