Q5.27: Could a gusset plate be added to the 4 sides of an interior column, and the floor beams will be in direct contact with these gusset plates and glued instead of direct contact with the column? (The gusset plate will be added to stiff 2 columns connections together in the floor height

A: Connections of floor beams may be in direct contact with the gusset plate rather than the interior column. However, please note that  a single gusset member may not be in contact with another gusset member and that gussets must be attached to at least two frame members already in contact (in your scenario, the two column members are already in contact).
