9.2.6.1 Material Properties for Deformation Analysis

Material Properties for Deformation Analysis

Concrete C 20/25
  • fc = fcm = 20 + 8 = 28 N/mm2
  • Ec = Ecm = 30000 N/mm2
  • εc1 = −2.0 ‰
  • εc1u = −3.5 ‰

Distorted for creep with (1 + φ) = 3.95:

  • Ec = Ecm = 7594.9 N/mm2
  • ε 2c1 = −7.9 ‰
  • εc1u = −13.8 ‰
Reinforcement steel B 500 S (A)
  • fym = fyk = 500 = 500.00 N/mm2
  • ftm = ftk = 550 = 550.00 N/mm2
  • Es = 200000 N/mm2
  • εsu = 25 ‰
  • αe = 200,000 / 30,000 = 6.67

Distorted for creep with (1 + φ) = 3.95:

  • αe = 200000 / 7594.9 = 26.33
