Objective: Develop understanding of how braced frames function as a lateral-force-resisting system; utilize tension member limit states to design braces. Braced frames in buildings are commonly idealized as "vertical trusses" in design (although, it is worth noting that their behavior in large earthquakes differs greatly from a truss). Use the elevation and typical detail below to design the braces on both stories as L-shapes with a single line of bolts if \( P_{\mathrm{E}}=180 \mathrm{k} \) (for this problem, only consider the factored load as a positive value). Your design should include a shape and number of bolts considering the limit states of gross section yielding, net section rupture, and block shear rupture. The bolts must be spaced at 3 " on center with centerlines located at least 1 " from the edges of the member and at least \( g \) from the outstanding leg (see Table 1-7A of the Specification).
