The solid steel-lined prestressed fiber-reinforced concrete (PFRC) slabs’ response to projectile impact was recently studied by the authors. This paper investigates the impact response of perforated steel-lined PFRC slabs when conventional steel rebars are replaced with perforated steel lining. The perforated steel-lined slabs were tested with a gas gun for their impact response. The PFRC slabs reinforced with steel rebars were also tested for comparison purposes. It was observed that the ballistic limit of two slab types (reinforced with rebars and reinforced with perforated steel lining) is almost the same for all percentages of steel fibers, which justified the equivalence of perforated steel lining with the steel rebars. However, the use of perforated steel lining resulted in improvement in the impact parameters (e.g., penetration depth, damage to the front and back faces, and mass ejected) of PFRC slabs compared to PFRC slabs with conventional steel rebars. The authors’ earlier proposed prediction formulas for the ballistic limit of solid steel-lined PFRC slabs were also updated for perforated steel-lined PFRC slabs. In the update, the perforated steel lining was replaced by an equivalent rebar system. The outcomes of the experiments and the predictions are in good agreement.
