A closed storage building shown in $($Figure $1)$ is located on

open flat terrain where $V=109m\frac{i}{h}.$ Take $K_e=1$ and

use the table of Velocity Pressure Exposure Coefficients for

Terrain with Low$-$Lying Obstructions below to determine $K_z.$

The side wall of the building is $20ft$ high, and each wall is

$60ft$ long. Assume the roof is flat.

Part A

Determine the two values of the design wind pressure acting on the windward wall at the height

of $0-15ft$ above the ground.

Express your answers in pounds per square foot to three significant figures separated by

a comma.

$P_{0-15}=17\mathrm{.}2,26\mathrm{.}5psf$

Incorrect; Try Again; $6$ attempts remaining

Part B

Determine the two values of the design wind pressure acting on the windward wall at the height

of $20ft$ above the ground.

Express your answers in pounds per square foot to three significant figures separated by

a comma.
