$($c$)$ Wall D resists a characteristic permanent load $(g_k)$ of $300k\frac{N}{m}$ and a Fig$\mathrm{.}02$: Plan of Shear Wall Layout

characteristic variable load $(qk)$ of $200k\frac{N}{m}$ at its base due to gravity loads such

as self$-$weight, floor loads etc.

The characteristic wind action in the East$-$West direction may be idealised as a

uniformly distributed lateral load of $10k\frac{N}{m}$ applied along the full $30m$ height

of the wall.

$($i$)$ Determine the peak compressive and tensile stresses at its base at

ultimate limit state.

$($ii$)$ Determine the reinforcement required at the base to resist the peak

tensile stress determined in $($i$).$ Clearly state any assumptions made.
