The maximum combined stress σmax when a column of rectangular section is subjected to an eccentric load P is given by :
Note: the eccentricity is about only the axis bisecting the width 'b'.
Where e-eccentricity of the load
A - cross sectional area of column
b - width of column
d - depth of column
1
σmax = \(\frac{{6Pe}}{{Ab}}\)
2
σmax = \(\frac{{P}}{{A}}\)
3
σmax = \(\frac{{P}}{{A}}\)(1 + \(\frac{{6e}}{{b}}\))
4
σmax = \(\frac{{P}}{{A}}\)(1 - \(\frac{{6e}}{{b}}\))
