3 At Service Load Calculators

Stress in Concrete Member with Non-Prestressing Steel at Service Load Having Compressive Axial Load
Go Stress in Concrete Section = (Effective Prestress/(Transformed Area of Concrete+(Modulus of Elasticity of Steel/Modulus of Elasticity Concrete)*Area of Reinforcement))+(Axial Force/Transformed Area of Prestressed Member)
Strain in Concrete due to Effective Prestress
Go Concrete Strain = Strain in Tendon-Strain Difference
Strain in Tendons due to Effective Prestress
Go Strain in Tendon = Strain Difference+Concrete Strain

Strain in Concrete due to Effective Prestress Formula

Concrete Strain = Strain in Tendon-Strain Difference
εce = εpe-Δεp

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.
