Abstract
A grid framework for a suspended ceiling wherein reinforced cross members are allowed to expand; without collapsing or buckling, during a fire. Clips at the end of the members create barriers that are successfully overcome, in stages, to relieve any excess longitudinal compressive forces capable of being built up by the reinforced members.
