This paper provides procedures for the analysis of steel-fiber reinforced concrete warehouse floor slabs. The increased flexural strength of steel-fiber reinforced concrete results in smaller thickness of slabs for a given loading. Therefore, emphasis is placed on the case of uniform loading which tends to cause uplift of the slab, a problem which is usually not serious with conventional concrete floor slabs. Expressions are derived for "critical" aisle widths based on flexural strength and uplift considerations, and design examples are given to illustrate the thickness design procedure (it is more economical to design for actual aisle widths where they are known, rather than for variable aisle widths that are based on theoretical "critical" aisle widths for uplift considerations).
