Critical Buckling Loads for Tapered Columns

Transactions of the American Society of Civil Engineers, 1962
Formulas and graphs for determination of critical elastic buckling loads of uniformly tapered columns having wide flange section, box section, and other cross-sectional shapes are presented; columns with pinned ends, fixed-free ends, fixed-pinned ends, and fixed ends are considered; critical elastic buckling loads may be obtained directly from graphs ...

Approximate Buckling Loads of Open Columns

Journal of the Engineering Mechanics Division, 1958
General equation for buckling loads of open thin-walled columns, applicable to any boundary conditions, considering coupling effect between torsional and bending bucklings; most general case of triple coupling may be treated as two double coupling cases without introducing significant errors; equations for columns restrained by flexible skin.

Approximate Derivation of Critical Buckling Load

Journal of Architectural Engineering, 2009
This paper proposes an approximate derivation for the critical buckling load of a column, based on the application of a uniformly loaded beam's midspan moment and deflection to the buckled column's rotational equilibrium. The curvature of a pin-ended member, when it buckles under axial load, is similar to the curvature assumed by the same member when ...

Buckling Load of a Stepped Column

Journal of the Aeronautical Sciences, 1951
A procedure is developed for computing the critical buckling load of a column having a finite number of steps with constant EI within each step. The procedure is applicable to columns with any end conditions and with loads applied within the span, as well as at the ends.

Improved Technique for Estimating Buckling Loads

Journal of Engineering Mechanics, 1984
An improved version of the Rayleigh technique is applied to prediction of critical buckling loads of prismatic columns, stepped columns, and tapered columns. Both the Rayleigh (curvature) or potential energy expression and the Timoshenko (deflection) or complementary energy are utilized and applied to predicting upper bounds.

Cylindrical Buckling Load of Laminated Columns

Journal of Engineering Mechanics, 1989
The cylindrical buckling load of a composite laminated column is derived from plate theory. The effect of lamina orientation is taken into account by treating the stiffness parameter as a matrix product rather than as a single value drawn from the definition of the elastic coefficients.
