Consider a $n=7-$storey building, $Bx=28m$ and $By=34m$ on plan as shown in figure above.

The roof and floors of the building are $275mm$ thick. Shear walls, intended to resist overturning are located at both ends of the building and are $t=300mm$ thick by bw$=4m$ wide on plan. The following characteristic imposed$/$wind actions act on the building:

Roof loading $=0\mathrm{.}6$kPa

Office floor loading $=2\mathrm{.}5$kPa

Partition loading $=0\mathrm{.}8$kPa

Wind $($horizontal$)$ loading $=1\mathrm{.}15$kPa

The characteristic weight density of reinforced concrete is $Yc=25k\frac{N}{m}?$
