Web17 Nov 2015 · The minimum net tensile strain for a non-prestressed flexural member per ACI 10.3.5 is 0.004. If the section in question has a net tensile strain between 0.002 (for a compression-controlled section with Grade 60 reinforcement) and 0.005, the phi factor is linearly interpreted between 0.65 (tied) and 0.90 or between 0.75 (spiral) and 0.90. WebThe average compressive strain at compressive strength is 0.49%, which is slightly higher than the traditional PVA-ECC (0.43%) (Wang & Li, 2005). The average result of Young's modulus of the PVA-ECC under compression is 19.22 GPa, which is close to that of the PVA-ECCs reported in previous studies with a typical range of 20–25 GPa (Li, 2008).
