Assuming the Wind load parameters below for the building, and using the Directional Method in ASCE $7$ Chapter $27,$ answer the following questions:

The natural lateral frequency, $f>1=>$ RIGID building

Risk Category III

Basic Ultimate Wind Speed $=175mph$

Exposure Category $"$C$"$

Flat land

Partially enclosed

b$)$ Using the appropriate ASCE $7$ table $($see the ASCE $7$ tables at the back of this exam booklet$),$ determine the velocity pressure coefficients $K_z$ and $K_h$ at the roof level of the onestory building.

$(5$ points$)$

$K_z($ roof $)=$

$K_h($ roof $)=$

$$

c$)$ Calculate the velocity wind pressures, $q_z,$ on the windward wall, and $q_h$ on the leeward wall in psf$,$ for the main wind force resisting systems $($MWFRS$).$ Assume $K_e=1\mathrm{.}0.(5$ points$)$
