Bending moment (kNm)

Therefore:

Ac = b . h
= .2 ×.3
= 0.0600 m²

h' = h - d'x
= .3 - .035
= 0.2650 m

b' = b - d'y
= .2 - .035
= 0.1650 m

Assumptions:
(1) The general conditions of clause 3.8.1 are applicable.
(2) The section is symmetrically reinforced.
(3) The specified design axial loads include the self-weight of the column.
(4) The design axial loads are taken constant over the height of the column.

Design approach:
The column is designed using the following procedure:
(1) The column design charts are constructed.
(2) The design axis and design ultimate moment is determined .
(3) The steel required for the design axial force and moment is read from the
relevant design chart.
(4) The area steel perpendicular to the design axis is read from the relevant
design chart.

Check column slenderness:


End fixity and bracing for bending about the X-X axis:
The column is braced.
\ ßx = 0.85 Table 3.21

End fixity and bracing for bending about the Y-Y axis:
The column is braced.
\ ßy = 0.85 Table 3.21

Effective column height:

lex = ßx . Lo
= .85 ×3

Therefore:

= .4 ×.4001
= 0.1600 m²

h' = h - d'x
= .4001 - .035
= 0.3651 m

b' = b - d'y
= .4 - .035
= 0.3650 m

Assumptions:
(1) The general conditions of clause 3.8.1 are applicable.
(2) The section is symmetrically reinforced.
(3) The specified design axial loads include the self-weight of the column.
(4) The design axial loads are taken constant over the height of the column.

Design approach:
The column is designed using the following procedure:
(1) The column design charts are constructed.
(2) The design axis and design ultimate moment is determined .
(3) The steel required for the design axial force and moment is read from the
relevant design chart.
(4) The area steel perpendicular to the design axis is read from the relevant
design chart.

Check column slenderness:


End fixity and bracing for bending about the X-X axis:
The column is braced.
\ ßx = 0.80 Table 3.21

End fixity and bracing for bending about the Y-Y axis:
The column is braced.
\ ßy = 0.80 Table 3.21

Effective column height:

lex = ßx . Lo

DESIGN
Zero shear is at (43.96 - 26.72) /11.94 = 1.444 m from left
M = 43.96 x 1.444 - 26.72 x 0.844 - 11.94 x 1.444²/2 = 28.48 kNm/m
d = 150 - 20 - 6 = 124 mm K = 0.0926 As = 593 mm²/m
PROVIDET12 @ 180 B = 628 mm²/m
Enhanced by 5.4 % for deflection T10 @ 400 T in span
