Strain Difference = (Strain in Prestress Steel-Strain in Concrete)
Δε_p = (ε_p-ε_c)

What is Strain difference?

The strain difference (∆εp) is the strain in the prestressed tendons when the concrete
has zero strain (εc = 0). This occurs when the strain due to the external tensile axial
load balances the compressive strain due to prestress.

What are the effects of Temperature on Prestressing Steel?

1 The mechanical properties of prestressing steel; ultimate strength, yield stress and elastic modulus; are not affected when ambient temperature varies over a reasonable range.
2 Extreme temperature conditions can seriously affect these properties; a sharp decrease in temperature might lead to improvements in strength and modulus, but deterioration in ductility and impact resistance.
