= 3,000 mm (both the ends are hinged)
Euler’s buckling load,
Say, central deflection,
A steel column of a hollow circular section of 200 mm external
diameter, 160 mm internal diameter and 7-m-long has to take a
20-kN load at an eccentricity of 30 mm from the geometrical axis.
If the ends are fixed, calculate the maximum and minimum stress
intensities induced in the section, taking
= 210 kN/mm
Moreover, calculate the maximum permissible eccentricity so that
no tension is induced any where in the section.
