Question : 128 of 200

Marks: +1, -0

The minimum eccentricity to be considered for an axially loaded RCC column of size 400 mm × 400 mm with unsupported length of 5 m is:

Solution:

Unsupported length = 5000 mm
Size of the column = 400 mm
Minimum eccentricity

=\L/500+\B/30

{\e}_{\min }={5000}/{500}+{400}/{30}=23.33 {\mm}

But, in no case, the minimum eccentricity should be less than 20 mm.
