Abstract:
An earlier paper demonstrated that the cover requirements given in ACI 216.1 will not consistently lead to adequate fire resistance of simply supported, unrestrained, slabs, with current load factors and reinforcement materials. This study leads to a suggested replacement for Table 2.3 of ACI 216.1. Greater cover thicknesses would be required for all fire exposure times beyond one hour, with significant increases for the uncommon design case of 4 hours required fire resistance.
