Loss in Prestress given Shrinkage Strain Solution

STEP 0: Pre-Calculation Summary

Formula Used

Loss in Prestress = Modulus of Elasticity of Steel Reinforcement*Shrinkage Strain
Δf_loss = E_s*ε_sh
This formula uses 3 Variables

Variables Used

Loss in Prestress - (Measured in Gigapascal) - Loss in Prestress is the loss found in the prestress due to shrinkage or creep or anchorage slip etc.
Modulus of Elasticity of Steel Reinforcement - (Measured in Gigapascal) - Modulus of Elasticity of Steel Reinforcement is a measure of its stiffness.
Shrinkage Strain - Shrinkage Strain is the value for strain caused due to shrinkage in concrete.

STEP 1: Convert Input(s) to Base Unit

Modulus of Elasticity of Steel Reinforcement: 200000 Megapascal --> 200 Gigapascal (Check conversion here)
Shrinkage Strain: 0.0003 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Δf_loss = E_s*ε_sh --> 200*0.0003

Evaluating ... ...

Δf_loss = 0.06

What is Shrinkage in Concretes?

Shrinkage of concrete is defined as the contraction due to loss of moisture. We know that concrete shrinks in volume when it dries up. This volume reduction takes place in the form of reduction of all dimensions. The shrinkage of concrete in prestressed members results in a shortening of tensioned wires and hence contributes to the loss of stress. The shrinkage of concrete is influenced by the type of cement, aggregates and the method of curing used.
