first bolts;
first connecting members bolted to an outer surface of one of the flanges by the first bolts such that the first connecting members contact the outer surface of said one of the flanges;
second connecting members bolted to an inner surface of said one of the flanges by the first bolts such that the second connecting members contact the inner surface of said one of the flanges;
a pair of gusset plates extending laterally outward from the column past the first connecting members at opposite ends of the gusset plates;
second bolts attaching the gusset plates to the first and second connecting members on opposite sides of the column;
wherein the second bolts include a first group of second bolts connecting the gusset plate to the first connecting member, and a second group of second bolts connecting the gusset plate to the first connecting member, the first and second groups of bolts being spaced apart from each other by a distance and free of any other second bolts between the first group and second group, the distance being greater than the separation of adjacent second bolts in the first group from each other or adjacent second bolts in the second group from each other, a space on the gusset plates between the first and second groups of second bolts being free of bolt holes; and
third connecting members attached to outer surfaces of the gusset plates by third bolts, wherein the assembly is free of a connecting member on the outer surfaces of the gusset plates between the flanges of the column.
