I have a case where a HSS5.00x0.250 round brace was cut 12" too short. The contractor/fabricator cannot apparently find another piece that is easily available. The piece is only about 14 feet long and is part of a 2-story X braced bay. They have asked whether they can use a piece of 5" STD A53 pipe instead. For the HSS, RyFyAg = 205.2 k. For the A53, RyFyAg = 292.3k. I can increase the throat of weld of the brace to the gusset plate, but I'll end up with a non-symmetrical brace configuration. Any comments or suggestions?
