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 Tendons due to Effective Prestress Formula

Strain in Tendon = Strain Difference+Concrete Strain
ε_pe = Δε_p+ε_ce

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.

How to Calculate Strain in Tendons due to Effective Prestress?

Strain in Tendons due to Effective Prestress calculator uses Strain in Tendon = Strain Difference+Concrete Strain to calculate the Strain in Tendon, The Strain in Tendons due to Effective Prestress is defined as the strain occurred on the prestressing tendons due to remaining prestress after the losses, ie. effective prestress or the prestress at service. Strain in Tendon is denoted by ε_pe symbol.

How to calculate Strain in Tendons due to Effective Prestress using this online calculator? To use this online calculator for Strain in Tendons due to Effective Prestress, enter Strain Difference (Δε_p) & Concrete Strain (ε_ce) and hit the calculate button. Here is how the Strain in Tendons due to Effective Prestress calculation can be explained with given input values -> 0.04 = 0.02+0.03.
