WebJoist and joist girder chords have a relatively low moment capacity. When these eccentric loads become large, chord designs will generate larger sections and/or expensive chord reinforcement. The most economical way to design for these induced axial loads is to provide a direct load path from the chords to the support or to another abutting member.
