For an ideally straight, exactly concentrically loaded beam or column, only a small force may be needed from an intermediate brace to reduce the unbraced length of a column or […]
EK597
Since it is impossible to quantify the variations in geometric imperfections, accidental eccentricity, residual stresses and material properties, it is impossible to calculate with certainty, the greatest reduction in strength […]

The function of a column baseplate is to distribute the column forces to the concrete foundation.
EK368
Of fundamental importance when determining suitable effective lengths is the classification of a column as either a sway case for which translation of one end relative to the other is […]
EK226
The buckling theory is based on the assumption that the ends of the column are pinned, that is, frictionless joints which prevent linear movement but which can rotate freely about […]
EK225
The Euler buckling theory makes no allowance for: Homogeneity of column material. Isotropy of column material. Variation of Young’s modulus and elastic-plastic behaviour of column material. Loading not axial. Residual […]
EK208
An ideal column is perfectly straight but real columns always have some imperfections which deviate from this ideal. The amount of imperfection to be expected varies with the type of […]
EK204
The effective length of a column is controlled by its end fixity. By effective length we mean that length of the column which is subjected to lateral buckling.
EK153
One of the most common methods of designing frames with simple joints is often used for rectangular frames with vertical (column) and horizontal (beam) members under the action of vertical […]
EK109
The typical proportioning of member sizes in tall rigid frames is such that girder flexure is the major cause of drift with column flexure a close second. Therefore, the most […]
EK108
The lateral deflection of a story-high rigid frame due to beam and column rotations may be considered analogous to the shear defections of a story-high segment of a shear wall.
EK43
The Euler formula is derived for a straight, concentrically loaded, homogeneous, long, slender, elastic and weightless column with rounded ends. It is assumed that this perfect column has been laterally […]
EK17
A column with some initial lateral deflection will exhibit non-linear behavior as the load is increased. The non-linearity is not significant at normal design loads, but it becomes highly pronounced […]
