I have a job where I have grid system where there is 6" grid mains and 2½" grid lines. In order to lessen the weight in the zone of influence of the 6" grid mains I have included additional longitudinal bracing on the 2½" grid lines. Is it acceptable to exclude the Zone of Influence of the Longitudinally braced 2½" Grid lines from the Zone Of Influence of the 6" Grid Mains? Does NFPA-13 address this scenario?
