7.4.1 - Axial Pressure and Bending

Section width cannot be less than 250 mm in rectangular section columns. However, the minimum thickness may be 200 mm for columns with I, T and L sections, and 120 mm for columns with box section. For columns with a circle cross section, the column diameter cannot be less than 300 mm. Also in all columns,
