A structural detail presents the layout procedure for bolt holes on a braced frame connection using gusset plates. The upper-most bolt-hole is established at distance L_bh from the lower-most bolt-hole, following 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, with reference notes coordinating with related connection details and concrete blockout locations. The overall procedure details the sequence for establishing bolt-hole patterns and minimum bolt tensioning requirements.
