A circular hollow column has an external diameter of 1.5 m and a wall thickness of 0.25 m. Both ends are fixed and it is 20.8
m high. Calculate the critical load in kN if Youngs Modulus for the column material is 200 GPa.
.A 5-mm thick mild steel plate is used to form a hollow column of 60 mm outside diameter. The column length is 1.2 m. Calculate the crippling load using Johnson’s Parabolic formula. Take modulus of elasticity and yield strength as 206 GPa and 330 MPa, respectively. Assume one end is hinged and the other end fixed.218212 N176745 N930094 N263252 N
To calculate the maximum axial loads for a column based on yielding and buckling
about both axes, and allowing for factors of safety.
The critical load P for buckling of a column depends on the vertical distance between
supports and how the column is connected to those supports. The length L in the
T'EI
formula Per
=-
is the distance between points of zero moment. For a pin-
L2
supported column, this is the full height of the column.
For a column that is not pinned at both ends, the points of zero moment are not at the
supports. The equation for the critical load can be modified to use an effective length
Le = KL, where K depends on the support conditions. For a column fixed at both
ends, K = 0.5. For a column fixed at one end and pinned at the other, K = 0.7
(Figure 1). The equation for the critical load then becomes
