The results show the ability of the composite deck floor slabs to bridge over the removed wall sections. The slabs were able to re-distribute the gravity loads to adjacent wall components, while some of the loads were picked up in tension by the stud walls above the slabs. The study provides a good understanding of the composite deck floor-cold-formed steel stud bearing walls building system in resisting progressive collapse.
