Abstract

This paper presents a strategy for achieving the required fire resistance in composite floor systems through the use of steel fiber reinforced concrete (SFRC). Both experimental and numerical studies were carried out to evaluate the fire performance of floor systems comprising of unprotected steel beams and concrete/SFRC deck slab. Results from these studies show that SFRC composite deck slabs develop significant tensile forces (through tensile membrane action) that transfer load from fire weakened steel beams to other cooler parts of the structure. Preliminary results indicate that the combined effect of composite construction and the use of SFRC under realistic fire, loading, and restraint conditions will provide sufficient fire resistance in steel beam-concrete deck slabs to eliminate the need for external fire protection.
