Problem: You are designing typical office building that is $2$ stories tall with a flat roof. Each

level of the building is $15$ feet tall. The building is located in a developed area of Los

Angeles with many other buildings around the site. The plan dimensions of the building are

$30$ feet by $30$ feet. The wind pressure distribution was determined previously in Assignment

#$4$ as $P_0=18\mathrm{.}1$ psf and $P_h=19\mathrm{.}6$ psf for this type of building.

Complete the following:

Determine the horizontal design static wind pressure $($psf$)$ at intermediate locations

$($mid$-$height of first floor $P_{0\mathrm{.}5},$ top of first floor $P_1,$ mid$-$height of second floor $P_{1\mathrm{.}5})$

Determine the resulting total force $($kips$)$ to the Roof $($TOP of the $2^{nd}$ floor$)$ and the

$2^{nd}$ level $($TOP of the $1^{st}$ floor$).$

Using $3$D equations of equilibrium, solve for the axial forces in the braces due to the

wind forces. This was studied in Structures I. Do the upper story force first, then

the lower story. Be sure to indicate tension or compression on these axial forces.
