Okada&Iguro [22] | ft(T, 100%) = 2.4 + 0.06 × fc(T, 100%)(6) | ft (T,100%), fc (T,100%) are the tensile strength and compressive strength of water-saturated concrete at low temperature, respectively |
Rostasy&Scheuermann [35] | ft(T, W) = γ × fc(T, W)0.67(7) | γ is coefficient: concrete in the air-dry state to take 0.3, water-saturated state to take 0.56, the rest of the state interpolation can be. |
Goto&Miura [17] | ft(T, W) = 0.214fc(T, W)3/4(8) | ft (T, W), fc (T, W) are the tensile strength and compressive strength of concrete at low temperature, respectively |
Takashi Miura [24] | ft(T, W) = 0.38fc(T, W)3/4(9) | |
Shi [33] | ft(T, W) = 0.0045fc(T, W)1.6588(10) |
