2. (a) A braced column which is 300 mm
square is restrained such that it has an
effective height of 4.5 m. Classify the
column as short or slender.

(b) The column supports:


(1) an ultimate axial load of 500 kN
and a bending moment of
200 kNm, or
(2) an ultimate axial load of 800 kN
and bending moments of 75 kNm
about the x-axis and 50 kNm
about the y-axis.
Design the longitudinal steel for both
load cases by constructing suitable
design charts assuming fcu = 40 N/mm2,
fy = 500 N/mm2 and the covers to all
reinforcement is 35 mm.
