Design the column shown in Figure $2$ using S$275$ steel grade between Levels $1$ and $2$ with $5m$

height.

Figure $2$: Column in simple construction.

a$)$ The calculation of design compression force is really important for you to select the

column size in your design. Therefore, formulate the design compression force from the

given applied loads at Level $2$ and Level $3.($CO$1,$ PO$1,$ C$2,$ WP$1)$

$[3$ marks$]$

b$)$ Justify and defend for the proposed universal column size $($UKC$)$ into your design and

check its nominal moment. $($CO$1,$ PO$1,$ C$2,$ WP$1)$

$[3$ marks$]$

c$)$ Classify for the cross$-$section classification of your proposed column $($UKC$)$ and

describe its simplified interaction criterion. $($CO$1,$ PO$1,$ C$2,$ WP$1)$

$[5$ marks$]$

d$)$ Justify for the adequacy of the buckling moment resistance for both major and minor

axis. $($CO$1,$ PO$1,$ C$2,$ WP$1)$

$[10$ marks$]$

e$)$ Clarify the resistance of the proposed member using the simplified interaction criterion.

Justify whether the resistance of the member is adequate or not. $($CO$1,$ PO$1,$ C$2,$ WP$1)$
