Method for converting a first type of concrete reinforcing material to an equivalent quantity of concrete reinforcing fibers for designing a reinforced concrete slab. Fibers may be steel or other materials. User determines whether a slab to be reinforced is a lightly reinforced slab; and then uses spacing theory to get a minimum fiber dosage for a given concrete slab thickness, if the slab is a lightly reinforced slab. User then uses an equivalent area of steel calculation to determine proper fiber dosage, if the minimum fiber dosage for a given concrete slab thickness is insufficient to give a residual strength factor greater than 30 percent. If minimum fiber dosage for a given concrete slab thickness suffices to give a residual strength factor greater than 30 percent, then user uses equivalent moment capacity calculation to determine a proper fiber dosage. Concrete design calculator may incorporate method and values.
