Beam $1$:

Span $8$m

Permanent load $=50$

Variable load $=60$

Beam $2$:

Span $9$m

Permanent load $=70$

Variable load $=80$

Column height $=5$

Height $=289\mathrm{.}1$ m

Tw $=19\mathrm{.}2$mm

Total design load $=1595\mathrm{.}25$kN

Beam $1$: $((50$x$1\mathrm{.}35)+(60$x $1\mathrm{.}5))$ x $(8/2)=630$kN

Beam $2$: $((70$ x $1\mathrm{.}35)+(80$ x $1\mathrm{.}5))$ x $(9/2(=965\mathrm{.}3$ kN

Question $1$: calculate the nominal moment about y$-$y and z$-$z axis $($i$.$e MED,yy and MED zz$)$

Using formula:

My$,$Ed $=(($h$/2)+100)$

Mz$,$Ed $=(($tw$/2)+100)$

Answer:

MED, yy $=82$kNm

MED, zz $=0$kNm
