TUF-STRAND FIBER DESIGN STUDIO

Based on the recommendations of ACI 544.4R, this calculator converts required steel reinforcement into an equivalent fiber dosage using either calculated steel tensile stress or reinforcement area from an existing slab-on-ground design. It is intended for applications where fibers replace conventional temperature and shrinkage reinforcement while providing effective crack control and maintaining slab durability and serviceability.

This calculator determines the nominal bending moment capacity provided by reinforcing steel at a specified location and converts that capacity into an equivalent fiber dosage using residual flexural strength values obtained from ASTM C1609 (fₑ₃) testing, enabling performance-based structural design with TUF-STRAND SF.

Using NRMCA verified Environmental Product Declaration (EPD) data, this calculator estimates and compares the Global Warming Potential (GWP) of fiber-reinforced concrete and conventionally reinforced concrete. The results help quantify potential CO₂eq reductions when using fiber reinforcement.

Available exclusively to registered users, this advanced engineering platform evaluates material properties, subgrade support, joint performance, and loading conditions - including point, line, uniformly distributed, rack post, and vehicle wheel loads. It optimizes slab thickness, determines the required TUF-STRAND SF dosage, and verifies performance under both serviceability and ultimate limit states.
