This diagram outlines the sequential layout procedure for a bolted gusset plate connection on a structural brace. The procedure establishes the lowest bolt-hole pattern on the bottom brace connection and locates the upper-most bolt-hole at a specified distance Lbh from the lower connection. A floating dimension applies to the upper end of the brace rather than the work point dimension Lwp-h. Additional notes reference specific details for bolt tensioning procedures and required concrete blockouts.
