🏗️ PTI / ACI 318 (0.5" / 0.6" Grade 270 Strand @ 80% GUTS / 33 kips, ΔL Inches ±7%)

Post-Tensioned Concrete Tendon Calculator

Calculate theoretical hydraulic jacking force and cable elongation for post-tensioned concrete structural slabs under PTI & ACI 318 Section 26.10: calculate initial jacking load (80% GUTS = 33.0 kips on 0.5" 270k low-relaxation strand), calculate required elongation (Inches ΔL = PL/AE within mandatory ±7% field tolerance), and PT stressing contracting profits.
