Q$1($a$)$ A tall building of width $20$ m and height $250$ m is subjected to wind loading due to a linearly varying mean wind profile with height. The mean wind velocity varies from $0\frac{m}{s}$ at the base of the building to $35\frac{m}{s}$ at the top. The building's fundamental frequency is $0\mathrm{.}18$ Hz $.$ Assume the mass per unit height of the building as $350{10}^{3}k\frac{g}{m}.$ The values of mean pressure coefficient on the windward face and the suction coefficient on the leeward face are $0\mathrm{.}8$ and $0\mathrm{.}2,$ respectively.

Assume an appropriate fundamental mode shape for the building.

Calculate the mean along$-$wind tip deflection of the building.

$($b$)$ Explain how you would calculate the peak along$-$wind tip deflection of the building in Q$1($a$).$
