Project Problem$-$Braced Frame for Building

Submit this in the "Project" dropbox

In the "project" folder on Blackboard, there are drawings that show the layout of the building we

will be using as a project throughout the semester. The project building has $3$ braced frames.

We will design braced frames $BF-1$ and $BF-2.$ These frames are identical and provide lateral

force resistance for wind directed towards the front or back wall. The ultimate wind loads are

shown on the diagram below. Design the lightest double angles for the x $-$brace at each story.

The x$-$braces are to be designed as "tension only". The braces are to be designed with a $\frac{3}{8}$ "gap

for a $\frac{3}{8^{\text{'}\text{'}}}$ gusset plate. Determine the best orientation of the angles $($LLBB or SLBB$).$ Provide

recommendations for filler plate spacing. For checking story drift, use a service load level equal

to $70\%$ of the ultimate wind loads. The drift limit for each story is H$/500.$
