The layout procedure for the upper bolt-hole pattern on a braced frame gusset plate connection. The upper-most bolt-hole is established at a distance L_bh from the lower-most bolt-hole, utilizing a floating dimension rather than L_wp-h at the upper end of the brace. The upper bolt-hole pattern is laid out similar to the lower pattern per the referenced details. Additional provisions note the requirement for a concrete blockout and reference specific tensioning procedures.
