Hollow Core Slab Calculator
Prestressed pre-tensioned hollow core units to SANS 10100-1 (SABS 0100-1 Ed. 2.2) Section 5. Enter any unit geometry, strand layout and span: section properties, prestress losses, transfer and service stresses, ultimate moment, uncracked and cracked shear scanned along the span, camber and deflection, and the maximum span the unit will carry — with a printable step-by-step sheet.
Generic units — not tied to any producer's range. Every clause cited on the sheet was read from the standard.
