Example Model with Sample Input
In this example, a concrete warehouse floor with joints spacing 20' o.c. a slab is subject to modular racking posts loads of 3,750 lbs each in a grid of 6' × 6'. The 6" slabs is supported on soil with a subgrade modulus of 100 kcf.
Figure 1 - 3D View and Plan View
The existing design called for a macro fiber dosage for TUF-STRAND SF as 4.9 lbs/yd3 per the table below (Courtesy of Euclid Chemical). Concrete strength is 4 ksi. In order to use the table, the reinforcement is to be of Grade 60 and placed in the top half of the slabs on grade.
To investigate or design a slab with fiber-reinforcement, spMats requires design parameters definition to have a single layer of reinforcement input. From the table above, for a 6" slab, an equivalent single layer reinforcement to the specified macro fiber dosage is #4 @ 16 in. which is equal to 0.15 in.2/ft.
